Falling - The Blackthorn Brothers, #5

I don't know who thought it was a good idea to put me in charge of protecting the gorgeous twenty-something year-old daughter of an heiress. Yet here I am, doing my best to keep her alive and out of a hitman's cross hairs. Unfortunately, the heiress refuses to listen to a damn word anyone says and she treats her daughter, Isabelle, like shit--which doesn't sit well with me. When the heiress gets herself killed, I can't say I'm heartbroken, given how horrible she's been to Isabelle.  And when Isabelle begs me to keep her alive, there's no way I can turn her down.
Not when I haven't been able to shake her from my thoughts from the moment I laid eyes on her. In typical Blackthorn fashion, I'm falling for her fast and hard. But there's still a killer on the loose, and it turns out the heiress had some secrets she'd have preferred to take to her grave.  Now, it's not just Isabelle's life that's at stake, but my heart, and there's a damn good chance I'm going to lose them both.*** This story has a Happily Ever After for the couple and can be read as a stand alone.  ***
