Han and Leia have kids. They're studying at Luke's Academy. Chewbacca's nephew is also there, as is the daughter of those people from The Courtship of Princess Leia. Expect many of Kevin J. Anderson's characters (Tionne, Kyp, Brakiss) to make an appearance as well. Basically X-Men with lightsabers.This work provides us with examples of:
An Aesop: One in every book, about drugs, racism, class, etc.
Broken Aesop / Aesop Amnesia: "Lighstabers" contains an egregious example. In the story Tenel Ka loses her arm in a lightsaber training accident as a result of being too proud of her own abilities and not putting enough care into constructing her lightsaber. Afterwards, she feels ashamed that she let her pride cloud her judgement. Good lesson. However, what does she do afterwards, not only in the same book but only several hours later? Refuses to wear a synthetic arm replacement. Why? Because she's too proud and has confidence in her abilities.
As in Lusa from The Crystal Star, of all origins. Unless there are two Force-Sensitive Centaurs named Lusa...
Also Tenel Ka, with her repeatedly-described "hard muscles".
Another oddly recurring theme is that of people being messily devoured by one thing or another, including wolf-men, carnivorous seaweed and giant flowers. Kevin J. Anderson is a bit of a Vore fetishist, it would seem.
Cybernetics Eat Your Soul: Averted with Qorl, who though equipped with a nasty-looking (and powerful) cybernetic arm to replace the badly -mangled original appendage is inarguably the most level-headed and moral of Brakiss's group.
Determined Homesteader / Doomed Hometown: Deconstructed in the first case, oddball example in the second. Everything built on the surface of Zekk's homeworld, Ennth, is destroyed in a regular, seven-year cycle by the planet's moon's elliptical orbit bringing it into the planet's atmosphere and touching off seismic cataclysms that last for an entire year, after which the inhabitants return from their space station refuges and rebuild everything from scratch. Anyone else would've moved to another planet a long time ago.
Old Soldier: Qorl. Overlaps with Shell-Shocked Senior and Crazy Survivalist as he's the lone surviving TIE Fighter pilot from the Battle of Yavin who's spent the last twenty or so years hiding out in the Yavin jungle waiting for the Empire to retrieve him.
Also Qorl being the crashed TIE Fighter pilot that Luke fought on the Yavin moon in the Marvel comics' Day After the Death Star, and the "Boba Fett" who appears in Shards of Alderaan being Ailyn Vel impersonating the bounty hunter.
Hand of Thrawn established that the Empire had signed a peace treaty with the New Republic four years prior to this series. The official explanation is that the Second Imperium, the antagonists of the Shadow Academy arc, was a Renegade Splinter Faction that refused to accept the peace.
