You can't go home again.. moreYou can't go home again...What do you do when home is a conspiracy that's been discovered and destroyed? When home is a planet in a star system that's gone missing? When home means working for the destroyers of galaxies? When home is a spaceship that's calling out to the enemy? Cantra 'yos Phelium isn't a quitter, but she has more than a little problem: the Enemy has accelerated its attacks and how do you fight an Enemy whose major form of attack is the de-crystallization of everything around itself? A smuggler with a rogue soldier for a co-pilot, and a tree with an attitude for crew, Cantra's the only one who can get close to the man who holds equations that might, that just might - thwart the Enemy. All she has to do is help a young pilot from a missing world, juggle a slippery promise she never quite made to a pair of wizards, and then forget who she is along with everything, and everyone, she's ever known. less
