Criss, a sentient AI, is born. Aliens come to steal him. Earth is defenseless without him.
Criss can fight for us if we set him free.
But can he be trusted?
Do we have a choice?

Crystal Deception is the first full-length book in the series, and Crystal Conquest continues the exciting story line as Earth’s heroes prepare for a world-ending invasion by alien forces.

Crystal Horizon (free here) is a short prequel to Crystal Horizon that serves as a series sampler for new readers who want to learn more. Best of all, it provides fans who have read the books a fun opportunity to reconnect with some favorite characters.
