A young-adult fantasy series written by Chris Wooding.The series follows the lives of twins Ryushi and Kia after their secluded home in the mountains is attacked and they find themselves in the world they've been sheltered from for so long. Unfortunately for them, this world (called the Dominions) happens to be controlled by the insane monarch King Macaan who is slowly gaining total control of the people. The rest of the series follows the efforts of Parakka in the beginning world of the Dominions and eventually its mirror world of Kirin Taq (controlled by Macaan's daughter, Aurin).Magic power in the series is based on how many "spirit stones" a person has. These (extremely expensive) stones are implanted along the spine shortly after birth by a group called Deliverers, and change at implantation depending on what the Deliverers feel the person will become. Kia and Ryushi each have six (as does their brother Takami). Kia's allow her to control earth, Ryushi's concussive force, and Takami's green fire. There are also people called Resonants who it is impossible to implant stones in who can travel between the two worlds.More information on this series' worlds and species can be found onThe Other Wiki.The series is inspired heavily by anime, as stated by Word of God in Wooding's webpage for the books.
This series provides examples of:
Alien Sky: Kirin Taq's sky is forever twilight, with the sun permanently eclipsed, and the Dominions is stated to have two moons.
Badass Normal: You discover at the end that the character Hochi has never had spirit stones, and instead gotten by on their own strength.
Bratty Half-Pint, Mouthy Kid & Class Clown: Gerdi, especially in Act One. Though, after he's betrayed and captured along with the rest of the group by Whist on Os Dakar and made to fight in the Snapper Run - a multi-level gladitorial arena pitting him against local wildlife - with Kia, he grows up and sheds most of these tendencies. Most of them. He still mocks Hochi from time to time...
Creepy Twins: In Kia's Vision Quest, she repeatedly sees Princess Aurin and leader of Parakka Calica as near-identical children with the same clothing and hairstyles, who speak in unison and are always holding hands. This is because the two are Splitlings, a pair of people born at the same time in the mirror universes.
Dungeon Punk: There's a pretty high level of technology in this world, like the Machinists' devices, the Lava-based heating system in Tusami City, and the transport devices powered by people with Pilot stones.
False Friend: Whist turns out to be one of these; not just once, but twice. The first time he encounters Parakka, he uses Kia's desire to find Ty to turn the whole group - Ryushi, Kia, Elani, Hochi, Gerdi and Tochaa - over to the Fallen Sun gang on Os Dakar. A year later, he leads Ryushi into the Maar Keep - Takami's residence as a Thane - where he is drugged and captured by Princess Aurin.
Fate Worse than Death: Resonants that Macaan captures are usually made into elite assassins known as Jachyra, an extremely painful process that leaves their minds tattered and their bodies more mechanical augmentation than flesh. In addition, they are unable to rise against Macaan, who can instantly end their lives using the trigger stone implanted in his forehead.
Another such fate for the Resonants takes place during Act Two's main battle: the Integration War. The Integration was Macaan's plot to bring a Keriag invasion force into the Dominions from Kirin Taq by using the combined power of his enslaved Resonants by imprisoning them in energy-rich caverns called Ley Warrens. By doing this, he would effectively turn the Resonants into an organic Stargate, bridging the Dominions and Kirin Taq.
Half-Human Hybrid: people of the Dominions (who in pretty much every aspect resemble humans) and Kirin Taq (who are the same as humans except for their yellow eyes and gray skin) are able to produce children together. It is revealed that Macaan is a halfbreed. Aurin also turns out to be quarter-Kirin. Though, the first half-breed to be encountered in the series is Jaan, one of the minor characters in Act Two, with all the social rejection it typically entails.
Kia from the sacking of Osaka Stud up until finding Ty on Os Dakar could qualify as this. Consumed by a desire for vengeance, she has to literally have the sense slapped back into her by Ryushi when she summons a golem to massacre a squad of Royalist Guardsmen on the streets of Tusami City. She spends pretty much the rest of the time being distrustful of almost everyone who isn't her twin brother and doesn't so much as shed a single tear about the loss of her family home until she reaches Os Dakar, six books (in the smaller format; only two books in the larger one) later.
Hive Mind: played straight with the Keriags, massive spider-like beasts with a shared consciousness whose only concern is for the well-being of the hive. Subverted with the race of the Koth Taraan who, although they share consciousness and knowledge, are all individual beings who resent having their connection compared to that of the Keriags.
Hive Queen: there are several Keriag hives, each with its own Queen. These Queens, however, are not solely connected to their own hive, but instead connected to the Queens and Keriags of the other hives. This is to such an extent that when one Queen is poisoned by Macaan, the others immediately agree to a lifetime of slavery, as losing one Queen would be like losing an arm for them.
Identity Amnesia: Act Three begins in the depths of a desert mine, following the viewpoint of an enslaved worker by the name of Mi'atte. As the days wear on, strange items start to inexplicably appear in her quarters. The unfamiliar fragmented memories eventually compel her to remember and mouth out a name to herself in the mirror: Kia.
(Not Quite A) Long-Running Book Series: In its originally planned format, Broken Sky would have fulfilled the second of the requirements for this by spanning a grand total of 27 books. However, after the first Act reached its end, the decision was made to condense the remaining 18 parts into a series of six "three-in-one" books and reissue Act One in the same manner, cutting it down from 27 down to nine. Outside fanfiction, Broken Sky has no Expanded Universe and the series only lasted three years (1999-2001) as opposed to ten-plus.
La Résistance: Parakka. The only form of real resistance against Macaan's empire.
Mind Rape: Princess Aurin has a strange being at her disposal known only as the Scour. Seeming to possess no facial features at all, the Scour possesses the power to tear through - or scour - a person's memories for gathering information.
"Then the Scour stepped into the doorway and all colour drained from [Ryushi]'s face. It wore a loose black cloak, belted at the waist, which swirled around its feet as it came. Its hands were held together in front of it, buried in its long sleeves. But its chalk-white face was unhooded, and there were no features there. Shallow indentations or slight lumps indicated where eyes, nose and mouth should have been, but the Scour possessed only a smooth skull of naked flesh, uninterrupted by the features by which humans recognised each other. There was something inexplicably horrible about their absence. But not as horrible as the paralysis which suddenly gripped Ryushi, pinning his heart to his ribs and making his arms go limp. Strange, then, that he still had the breath to scream as the Scour clamped its fingers around his face and began to tear and shred at his memories..."
Mirror Scare: the Jachyra actually travel through mirrors, and as such there are numerous scares with one coming out of a reflective surface.
Our Dragons Are Different: the Wyverns of the books only have two legs, and although they can be bonded with human riders, they are presented more as beasts than sentient companions.
Disappeared Dad: Macaan seeks to conquer the world to give to his daughter to prove how much he loves her. These efforts cause her to see him rarely while she is being raised by various nannies, and she resents any attempt of his to be a "father" to her.
Missing Mom: Kia and Ryushi's mother never returned from an expedition when they were children. turns out she was killed for being a Parakkan. Also, Aurin's mother dies from the same disease that killed Macaan's parents.
Nominal Hero / Unlikely Hero: Their home was burned to the ground by Macaan's forces, their father was murdered by a member of Aurin's court, Ryushi and Kia join up with Parakka, who spark a civil war with the Royalist army and are involved in a number of pitched skirmishes. So you'd expect one of the twins to land the killing blow on the man responsible for everything, right? Wrong. Out of seemingly nowhere, Whist shows up and lands one of his razor discs right between Macaan's eyes. Bet you didn't see that one coming!
Power Incontinence: Ryushi at the beginning of the series has no control over his immense power, and inevitably burns himself out anytime he uses it.
Power Limiter: the aforementioned spirit-stones' power is nullified by "Damper Stones".
Title Drop: There is no indication of what "Broken Sky" stands for until the end of Act One when the dying Tochaa gives Hochi his pendant and it is revealed to be a translation of old Kirin meaning something divided with the hope for eventual unity. By the end of the series, the something is revealed to be the worlds themselves. The pendant - in an abstract manner - depicts the shattering (breaking) of the sky as the Dominions and Kirin Taq were seperated.
Took a Level in Badass: Ryushi. The latter two Acts have him learning how to better control the power granted by his Spirit Stones and, eventually, fulfilling a childhood dream to own/be bonded to his own wyvern: Araceil.
The Dark Side: Takami took on the mantle of the Spirit-Masked Warrior and pledged allegiance to Macaan's Royalist cause, becoming a member of nobility in return (the Thane of Maar).
In the final part of Act Three, the revelation of his reasoning transforms what seemed like a simple power grab into a complex mixture of Screw Destiny and a Self-Sacrifice Scheme. Believing the universe to be one giant exercise in predeterminism orchestrated by the Deliverers and the pah'nu'kah - the ritual by which they implant newborns with Spirit Stones - Takami decided that the best and only way for his father's dream of deposing Macaan and freeing both the Dominions and Kirin Taq was to betray Parakka in the biggest way possible. By destroying his own family home and murdering his own father, he set his younger siblings on a three-year journey that eventually brought them to become an integral part of Parakka and succeeding where he thought his father would fail without his assistance. In his own words: "My honour was the sacrifice I made to free the worlds."
The Reveal: The Spirit-Masked Warrior, the one responsible for leading the destruction of Osaka Stud and murdering Ryushi and Kia's father, Banto, finally shows his face at the end of Act One. It's Takami.
The Trickster: Gerdi's ability practically revolves around this. His Noman spirit stones allow him to conjure illusions, altering the perceptions of select groups of people. Suffice to say, his use of this to startle Elani and his flippant personality go hand-in-hand.
Vision Quest: before the Koth Taraan will aid Parakka, they want to test one the group's representatives to see their motives. Kia accepts and enters a vision quest under the head Koth Taraan's observance.
