The Shark Island Mystery (Xtreme Adventure)
By M. A. Harvey.
Description
Two boys are kidnapped and held for ransom in Indonesia. Left on an island surrounded by sharks with no obvious way of escaping, they explore the area and find a secret cavern that is obviously the kidnappers' base. There they hatch a daring escape plan, but not before discovering some very strange shark objects. They know that they can only join the Xtreme Adventure group if they can figure out what these objects are, escape from the cavern, and apprehend their kidnappers. But the odds seem to be overwhelmingly against them. - from Amzon
