Put your finger on the Georgia-Florida state line and drag it east until you hit the ocean. Right there, under the tip of your fingernail, is a slice of paradise known as Crab Island. Jacqueline "Jac" Dawson rolls over the old wooden bridge onto Crab Island after a ten-year absence and one ill-advised marriage to find the landscape and locals of her colorful, eccentric, perfect home unchanged. But just as she and her son, Milo, settle into Unit 5 at The Pink Mermaid Motel, murder and moonshine rip Crab Island open at the seams. Old family grudges wash up on shore, gossip slips between the palm fronds, and Jac finds herself at the center of a tangled web where freeing a murderer is the only way she can save her child's life.
