The Heart of a Killer - Secrets and Sins, #1

Dante Renaldi thought coming home from active duty would mean he could settle down. Instead, he's dropped right into the center of a murder-one bearing a mark he's seen before-on a night long ago. The last person Detective Anna Pallino thought she'd see again is Dante Renaldi, especially when a horrifying blast from the past in the form of an all too familiar murder rears its ugly head. That long ago night, she survived an attack thanks to Dante, and she wants to trust him as much now as she did then.
But as bodies pile up, Anna wonders if the man she owes her life to-the one she's falling in love with all over again-might want her dead?
