Aliens, Spies, AI, Romance, Battles in Space!
The Crystal Series books are futuristic thrillers of action and adventure that include all elements from the list above. Read them to enjoy engaging characters, pulse-pounding action sequences, and plot lines with surprises.
Criss, a four-gen AI crystal with the cognitive ability of a thousand humans, is the overarching personality in the series. Hard-wired to protect and serve his human leadership team, Criss is able to project his awareness through the web, and so we find him at the center of each story’s intrigue.
The team includes Dr. Jessica “Juice” Tallette, the crystal scientist who created Criss; Cheryl Wallace, an ex-captain of the Fleet space cruiser Alliance; and Sid, a one-time covert spy for the Defense Intelligence Agency, who now helps Criss protect Juice and Cheryl while they all strive to keep humanity safe.
Crystal Deception is the origin story of the series—it tells how Criss, a four-gen AI, was created, and how Sid, Cheryl, and Juice came to be his leadership. The excitement begins when alien aggressors—determined to take Criss for themselves by any means necessary—present a mortal threat to Earth. Our heroes fight to repel the invaders, and in the process discover why they will forever be joined as a powerful team.
Crystal Conquest continues the adventure started in Crystal Deception. The aliens are down, but by no means out. And this time they return for revenge. Led by an AI goliath, the aliens are determined to vanquish Earth. Can the team stop them before it’s too late?
Crystal Rebellion takes place on Mars, and the threat comes from three AI crystals left behind after the last alien invasion of our solar system. Join the adventure as our heroes struggle to save humanity and soon realize they need to save themselves.
Free: Crystal Horizon is a short prequel to Crystal Deception that serves as a free series sampler for new readers who want to learn more. Enjoy a mini-adventure that introduces you to Sid and Cheryl at the time when they first meet. It’s a great way to sample the writing style. And it provides fans who have read the books a fun opportunity to reconnect with some favorite characters.
