Arkadian Skies: Fallen Empire, Book 6 (Unabridged‪)‬

With the man who kidnapped her daughter imprisoned aboard her ship, Captain Alisa Marchenko is closer than ever to reuniting her family. But her new guest has been in a coma for weeks, with the secret to her daughter's location locked away in his mind. She must find a way to sneak him into a state-of-the-art hospital on Arkadius, a planet in the heart of Alliance territory. Not an easy task when she and the cyborg Leonidas, her most trusted ally, are wanted by the Alliance army.

As if that mission weren't daunting enough, the Staff of Lore has appeared on the planet. As has the man who stole it: Alisa's father.
