Citadel: Paths in Darkness. Citadel, #2

The real strangers are within. Book Two of the Citadel series. A MIND DIVIDED. A HOLLOW VICTORY. A NEW SPECIES. Against all odds, on an unchartered world, the souls of First Colony have been restored to life, and a centuries old wrong has been righted-sort of. On the planet's surface, a young woman struggles to reclaim her mind from the strange aftereffects of the cancellation wave. High above, the struggling colony's last hope of going home slowly falls from orbit, and two men face death to prevent it. And as the human colonists and their Esool captain struggle for survival, a new species emerges that can be the colony's savior-or its most dangerous enemy. As if it needed more. "I opened one of [Kevin Tumlinson's] novels and immediately was hooked.
I mean, he knows what he's doing. A writer who, bless him, knows how it's done."- Orson Scott Card, Hugo and Nebula Award Winning Author of Ender's Game "Few writers can blend science, history, and sheer suspense the way J. Kevin Tumlinson does. He's a true craftsman of the thriller, and a storyteller with both vision and heart. Every new book is an adventure that will keep you up all night."- Kevin J.
