His Reward (Banachi Family Book 1) by Winter Travers

Blood or not, the Banachis are family… When a typical day turns into an unexpected meeting with Kitty, Princeton quickly realizes he’s got something good right in front of him. Something he doesn’t want to let go. As a ghost from his past waltzes in without warning, threatening to take away Kitty, Princeton knows nothing will happen to Kitty and her family as long as he’s breathing. Kitty may not be blood, but she’s family now, and the Banachis do anything for the family. Anything.
