Sail - James Patterson

As Peter Carlyle, a smooth-talking, super-successful lawyer, waved his family off on a sailing holiday, all they had in mind was lying back and relaxing. But as a violent storm broke out, an explosion caused the boat to vanish without a trace and the family were lost, presumed dead.

Until now. When a message in a bottle is washed up on a shore, it becomes apparent that there must have been at least one survivor.

But all is not as it seems. The race is on to rescue the Carlyles, but does everyone looking for the family really want to find them alive? Survival may be the least of their concerns. In fact, being found may be the last thing they should be hoping for.
