Welcome to the Prospero Keys (or as the locals call them: the Ghost Keys), a beautiful chain of tropical islands on the edge of the Bermuda Triangle. Rain Cacique is water-skiing with her two best friends Charlie and Miranda when Rain sees her father waiting for her at the dock on the pier. Sebastian Bohique, her maternal grandfather, has passed away. He was the only person who ever made Rain feel special. The only one who believed she could do something important with her life. The only thing she has left to remember him by is the armband he used to wear: two gold snakes intertwined, clasping each other's tails in their mouths. Only the armband...and the gift it brings: Rain can see dead people. Starting with the Dark Man: a devilishly handsome World War II fighter pilot who looks more than a little familiar: 'Bastian's spirit. It turns out granddad's armband wasn't just for show. It was a Zemi. A talisman of power created by the Arawak Taino Indians who originally inhabited these islands. When Rain's grandfather died, his spirit passed into the zemi.
Now her grandfather's ghost is determined to prove to her just how special she is by revealing the Ghost Keys' hidden world of mystery and mysticism, intrigue and adventure.
