Bait
(Book)

"Six strangers wake up on a remote island in the Florida Keys with no memory of their arrival. They soon discover their common bond: all of them are heroin addicts. As the first excruciating pangs of withdrawal make themselves felt, the six notice a yacht anchored across open water. On it lurk four shadowy figures, protected by the hungry sharks that patrol the waves. So begins a dangerous game. The six must undertake the impossible--swim to the next island where a cache of heroin awaits, or die trying. When alliances form, betrayal is inevitable. As the fight to survive intensifies, the stakes reach terrifying heights--and their captors' motives finally begin to emerge"--,Provided by publisher.
