Here Today Gone to Maui, Hailey - I Got Your Back, Hailey, #4

A relaxing day on her favorite beach on Maui comes to a screeching halt when Hailey finds a little girl wandering alone, searching for her mother. When she gets the child to her father and discovers who he is, their vacation is officially over. Parker has no choice but to once again bring in Amanda and Hunt (from Hunter's Find) to help. Amanda is the one who helped this man leave his New York life behind.
As they struggle to find if his previous mob involvement had anything to do with his wife's disappearance, they discover her father has secrets of his own. The circle of deceit stretches over oceans, with too many players to let the family safely return home. Trusting anyone is a luxury even Parker can't afford. Drug activity, property wars, and more secrets from the past come back to haunt them all.
