Katie Cooper's recent disappearance isn't a big shocker because her friends know that she'd been bent on skipping town. Little does anyone know that she's spending her days chained up in a clearing on an uninhabited island off the Georgia coast after being abducted at knife-point by a psychopath.
All Bobby Steele wants in life is some respect for his rock band-and to put his hometown of Savannah, Georgia on the map of cities renowned for their live music scene. But just when it looks as if this dream may be one step closer to reality, a killer strikes in the nearby gambling town of Salt Island.
The murderer, dubbed the "Salt Island Slasher" by the local media, toys with investigators by leaving strange messages in his victims' throats. Bobby's lifelong friend and sailing partner, Jim Ferguson, uses his family connections with the local newspaper to obtain the contents of these supposedly top-secret messages. Bobby is the only one who can glean anything meaningful from the mysterious words, and time is rapidly running out for him to prevent the next victim's agonizing demise.
The two friends use their wits and sailing skills to deal with a persistent enemy from the past as they work together to prevent the Salt Island Slasher from striking again.
