Broken Arrow by Chelle Bliss

Annie Hancock is finally following her dreams, studying for her graduate degree to become a professional artist. But when someone starts to leave threatening notes around her studio and dorm, Annie can’t help but wonder…who’s after her and why? She doesn’t know who to trust or keep herself safe.
Arrow has been grinding for years as a bounty hunter and private investigator. After setting down roots and opening his own office, his business doesn’t take off the way he’d hoped. Just when he’s about to change course, a beautiful woman is in desperate need of his services.
But what starts out as a simple assignment becomes more complicated when they’re forced into hiding. And as the threat gets closer, and the attraction becomes hotter, they’ll need to decide if what they have is real or driven by danger.
