Unwilling Accomplice (New Orleans Detectives #5)
Melanie Atkins

Marcy Moretti believes that anyone can be redeemed, until she witnesses a murder at the hands of her ex-husband and is forced to go on the run with her young son . The only person who can help her is Joe Riso, her former brother-in-law, a detective staggered by the loss of his wife and daughter. If he's going to protect both Marcy and her boy, he must first find a way to unfreeze his icy heart—and along the way, find his own redemption.
