A girl.
Her dog.
A riddle they must solve to survive.

Lexi Donovan is an elite hacker whose world flips after her mentor is murdered. Armed with snark, grit, and the shepherd at her side, she delves into the world of bits and bytes to find the serial killer's identity.

Wading through his digital betting arena on the dark web inadvertently makes her the next target.

Ethan McAllister is a police detective hard-wired for justice. Unable to find the meddlesome hacker whose anonymous tip led him into a firefight, he's unsure if she's playing amateur sleuth or luring him closer for the perfect kill.

Sparks fly from their first meeting as they navigate the dark labyrinth surrounding a murder game of wit and bit coin where Ethan must choose whether to trust his badge or his heart.

"This could be James Patterson, Lee Child, and Tess Gerritsen rolled into one, but the dark, twisted methods used by the serial killer could surprise even those readers." - San Francisco Book Review
