Threshold — Vivien Dean

Sutter is a vampire on the run. After barely escaping the hunter his sire sent after him, he makes it all the way to the middle of nowhere, Oregon, before the approaching sunrise forces him to stop. He intends only to rest, then hit the road again as soon as night falls, but that plan falls apart when the motel's maintenance man discovers him passed out on the bathroom floor.

Ex-Marine Max Rowell hasn't had a purpose in life ever since coming home from the Gulf. Though he works at his father's motel, drifting through days that bleed endlessly into each other, it takes discovering an unconscious guy who looks like an angel but has clearly been through hell to give him new purpose.

Max isn't letting Sutter go anywhere until he's healed, but Sutter needs more than a warm bedside manner to get stronger. Though they strike a deal, the clock keeps ticking, and sooner or later Sutter will need to run again, or risk putting Max's life on the line when Sutter's past catches up to him...
