Atlanta homicide detective Patrick 'Tick' Kelly turned his back on the world the day his wife and children were murdered. Abandoning his city and his career, he holed up in a beach house on Mango Key, Florida, and drowned his grief in Jack Daniels. Now sober and a bestselling author, Tick would gladly stay a recluse forever if his brother Pete didn't keep trying to drag him back to the land of the living. After years of sacrificing her personal life in favour of her DEA job, special agent Kate Rush resigned and moved back to her native Miami. But the unofficial assignment that has just come her way is too intriguing to pass up. She and a fellow ex-agent are relocated to Mango Key to keep an eye on an imposing, mysterious fortress believed to be at the centre of a human trafficking ring. At first, the Kelly brothers are suspected of involvement, but Kate is sure Tick poses no danger - except for the slow-burning gaze that makes her breath catch and her heart race. Tick finds himself fascinated by Kate's investigation - and by her inviting mix of courage and kindness. Teaming up, they uncover a web of betrayal, blackmail, and ruthless greed. And as danger mounts, Tick realizes how far he'll go to protect the rare and surprising gift that's come his way: a second chance at a happy ending.
