In this crossover event between the Star Wars mainline comic and the Doctor Aphra series, Luke Skywalker teams up with Doctor Aphra on a mission to the Citadel of Ktath'atn (also known as the Screaming Citadel) to visit the Queen and unlock the secrets of the Eternal Rur, an ancient Force user trapped in a strange green crystal. However, they are met with more questions than answers when the Queen launches a plan to control Luke and his comrades with a horde of Abersyn symbiotes—a larva-type species with the ability to control the mind of its prey with a single bite. Luke, Doctor Aphra, and the rest of the Rebels who mount a rescue mission must all work together to defeat the Queen and her minions if they are going to survive...
A rebel pilot and a rogue archaeologist delve into the darkest shadows of the galaxy side by side, as Luke Skywalker reluctantly teams up with Doctor Aphra! The not-so-good Doctor will make Luke an offer he can't afford to pass up...one that leads him to a very rare gathering at the heart of the infamous Screaming Citadel! Will Luke find what he's looking for? Can Aphra be trusted? Or will they both wind up victims of the Citadel's queen? And as this unlikely duo steps right into the lair of one of the most powerful, reclusive and dangerous women in the galaxy, can Han and Leia be far behind them?
