Deep Dark Lies - Raquel Byrnes

After surviving a violent childhood tragedy and building a career hunting the monsters who shaped her past, one reckless night nearly ended everything. Now, two years later, Agent Ava Cortes is buried in the CBI's white‑collar division-until her former boss pulls her back into the world that almost destroyed her.

Special Agent August Blake has four victims and no leads. Desperate to stop the next murder, he turns to the one person he trusts to see what others miss. Brilliant, relentless, and infuriatingly intuitive, Ava can crack the case. But will she be fast enough?

The investigation turns into a deadly race for survival when an early snowstorm traps everyone in the small town of Black Oak. Including the killer.

But they're not the only hunter on the mountain.
