Bound By Duty by Valerie Hansen

Assignment: Single Mum Surveillance!

Her serial killer brother's escaped – and it's single mum Zoe Sullivan who's under suspicion! Sgt. Linc Colson trusts two things: his instincts and his Rottweiler K–9 partner, Star – and certainly not the pretty face he's assigned to monitor. He's done everything to keep her from getting under his skin – now he must stop those who want to put her six feet under.
