Deep Blue - Randy Wayne White

\nDoc Ford has long lived a double life. But in this electrifying New York Times bestselling novel, it may finally have caught up to him... \n \nOn a moonless night on Sanibel Island, Florida, marine biologist Marion Doc Ford carefully watches a video of a hooded man executing three hostages. The man is an American working with ISIS, and in the next few days, it'll be Ford's job, as part of his shadowy second life, to make sure the man never kills anybody else again. \n But a lot can go wrong in a few days, and Ford has no way of knowing that not only will the operation prove to be a lot more complicated than he has anticipated, but that he'll end up bringing those complications back with him to the small community of boaters, guides, lovers, and friends in Dinkin's Bay, where he's long made his home. \n \n Someone has taken Ford's actions very personally, and now no one there is safe--least of all, Ford himself.\n
