On a whim, Grady Kendall applies to work as a live-in caretaker for a luxury property in Hawaiʻi, as far from his small-town Maine life as he can imagine. Within days he's flying out to an estate on remote Hokuloa Road, where he quickly uncovers a dark side to the island's idyllic reputation: it has long been a place where people seem to vanish without a trace.

When a young woman from his flight becomes the next to disappear, Grady is determined--and soon desperate--to figure out what's happened to Jessie, and to all those staring out of the island's "missing" posters. But working with Raina, Jessie's best friend, to uncover the truth is anything but easy, and with a sinister presence stalking his every step, Grady can only hope he'll find the answer before it's too late . . . and that it might hold the key to what's been terrorizing the island all along.
