She is most definitely a chip off the old Shake Davis block. In fact, her Dad is more than a little proud of his daughter, who is both a research scientist oceanographer at the famed Woods Hole Institute and a U.S. Navy Reserve officer. When Tracey Davis is called to do her annual active duty stint at the Navy’s diving center in the Florida panhandle, her retired Marine father thinks its a great opportunity where his only child will be well-occupied—and out of harms way. He’s right and wrong. Lt. (j.g.) Tracey Davis is well-occupied leading active duty sailors at the base Ocean Systems office, but she’s hardly safe. When an old friend from her days working in Belize shows up looking for one of the girls they saved from sex traffickers in Central America, Tracey finds herself in very deep and dangerous waters—full of marauding sharks and deadly human predators.
