Lethal Balance - Sons of the Survivalist, #2

His name means hunter. Once the best assassin in black ops, Cazador is now the best at saving lives.  His path has changed from seeking bloody vengeance to running a health clinic in Rescue, Alaska. He will never again risk loving someone he can't protect. His mother and sister were murdered in front of him, his fiancée slaughtered in a war zone.  Despite his popularity with women, he's determined to remain unattached.
His heart can bear no more loss. Unfortunately, the universe isn't listening.  First, his brother hires JJ, a fiery-haired, tough cop who lives on the edge of danger and has the biggest heart of anyone he knows.  And then, his disreputable past returns in the shape of an adorable, foul-mouthed nine-year-old daughter.  Now he has two loved ones to protect. An impossible task, because.Life is dangerous.
Especially in Alaska. Ms. Sinclair is a comfort read for me. She knows how to give me heroes who can take charge but in that protective, not possessive way that I love and heroines who may suffer but have that inner strength that makes them survivors.~ After Dark Booklovers
