Stalker in the Shadows (Sonoma, #3)

Lately, nurse Monica Grant feels she's being watched. Followed. And then she receives a threatening letter— accompanied by a dead snake. If she doesn't stop her plans to open a free children's clinic, she'll end up dead, too. Terrified, Monica turns to former lawman Shaun O'Neill— who believes the same madman murdered his own sister five years before. She understands how much it means to the handsome, heart-guarding man to save her—and her dream. Even if he has to lure a deadly stalker out of the shadows— straight toward himself.
