Upon finding a message from her mother, she goes to the New 2 (New Orleans reconstructed after some hurricanes) and realizes nothing is as it seems.
Be wary of unmarked spoilers. This work contains examples of:
Good Is Not Nice: Oh so very much. Bran spends most of his time fighting, sparing and almost using inappropriate words in front of young children. Josephine is an outright jerkass who admits to tricking Eleni and turning Theron over to Athena. Pretty much everyone on the side of good qualifies. Not even Ari is not nice; she openly taunt Gabriel and admits she is fine with Theron making Josephine pay for what she did one day.
Gorgeous Gorgon: Ari is described as eerily beautiful, but is she does turn into a full-blown gorgon…
Hereditary Curse: The cause of nearly every problem in Ari’s life, as everyone wants to kill her because, as a future gorgon, she is a god-killer.
He Who Fights Monsters: τέρας hunters are this, as while they are meant to protect the gods from monsters, but they ended up being even crueler to the "monsters", who are in fact people who have succumbed to curses of the gods.
I Did What I Had to Do: Athena might be a victim of this. Everything she has done, she has done to get her son back.
Ari, as well. She knows most monsters were once human, but she kills many just to get to Athena whenever a fight breaks out, and admits she'd do anything to kill her.
I Don't Want to Die: Athena begs Ari to save her when she starts turning to stone, all while holding her resurrected baby for the first time in a thousand years.
In the Blood: Ari has her father’s instincts as a hunter, as proved by her reaction to being threatened. She snatches the hunter's blade when it falls and kills him with it, without even being able to see.
Kill the God: Ari swears to commit deicide at the end of the first book, after learning
Manipulative Bastard: Athena is the greatest, followed closely by Josephine, who’s supposed to be a good guy.
The full extent of Josephine's schemes is alluded to when she manages to hide the Hands from virtually everyone, even from the gods. Sure, it didn't end particularly well for her, but the Hands were only found because she left a cryptic message to Sebastian when she invited him to Church.
Mentor Archetype: Michel becomes Ari's legal guardian, Bran trains her in the art of fighting and her father Theron teaches her on how to use her hunter powers.
My God, What Have I Done?: Ari, after stabbing and killing the hunter sent against her. She did not know what he was, and she genuinely feared she had killed a man with his whole life ahead of him.
Also when she beheads a monster in the battle at the cemetery, momentarily freaking out at how effortless it was once she got her hands on a sword.
And when she turns Sebastian to stone.
Athena of all people reacted like this when she realized she had just had a gorgon kill her baby in her attempt to kill Zeus, and she spent a thousand years trying to get him back.
Necessarily Evil: The Novem have done some… questionable things, capturing anyone who might be useful to their fight. Josephine betrayed Eleni and Theron, handing him over to Athena and leaving Eleni and Ari pretty much defenseless.
No Name Given: Eleni’s mother and the gorgon who killed Athena’s child, though neither appear physically.
Oh Crap: Athena, when she realizes Ari is turning her to stone. It does not work, but still.
Our Vampires Are Different: Vampires such as the Arnauds and the Baptistes are different from the soulless revenants, as they are Born instead of Made.
She Knows Too Much: Josephine, of all people, is implied to have fallen victim to this, and though the details of her death, even who killed her or exactly why, are never revealed, she was killed just as everyone planned to ask her about the Hands.
Josephine might qualify, as she betrayed many of her allies to achieve her goals, and though the exact reasons for her actions are never fully revealed, she did save the Hands from falling into the wrong hands.
