Hitting Black Ice by Heloise West (M/M)

ER physician's assistant Hunter guards his heart carefully, but that doesn't stop him from falling for Shawn, the front desk clerk. He keeps his distance from relationships for a reason, but just can't help himself when it comes to Shawn.

Shawn is on the run from the law and love to protect himself and anyone else involved. One man is dead because of him, and his life now is simple and easily thrown into a bag at any hint of danger— until he meets Hunter and he no longer wants to run.

Forced into a hostage situation, buried passion explodes in the aftermath, and sex in the supply closet brings their hearts back to life. Tentatively, step by step, they begin to explore a relationship together until the past catches up with Shawn.
