Desert Pursuit by Jennifer D. Bokal

His mission? To protect her — no matter what it takes.

Brand-new Texas Law operative Theo Fowler has one mission: to take down deadly hacker Seraphim. But in the process, he’s got to battle Seraphim’s partner — a terrifying serial killer in pursuit of the child he had with his former flame, Anastasia Pierce. Somehow, Anastasia has kept the child a secret for years — but now the murderer is hot on her trail. With cybersecurity guru Theo by her side, she’s got a fighting chance of survival. Yet somehow the serial killer seems to know their every move, and Theo and Ana don’t know who to trust…except one another.
