Torch Ginger: (Paradise Crime Mysteries, Book 2) (Unabridged‪)‬

If J.D. Robb's In Death series went on location with Kaui Hart Hemmings's The Descendants, you'd have Toby Neal's Torch Ginger.

The island of Kaua'i is remote jungle, golden beaches, and ancient culture - but transients are disappearing in paradise, and only Detective Lei Texeira notices. Lei transfers to the island of Kaua'i, where she uncovers a pattern of disappearances that may be related to a bizarre cult - or is it just one madman at work? In Lei's world, everyone is guilty until proven innocent. In the midst of the biggest case sleepy Kaua'i has ever seen, Lei must also untangle the mysteries of her heart and discover who she loves.
