Terror at Forbidden Falls — Lee Roddy

A monster wave crashes over the highway. Josh Ladd, his dad, and Tank Catlett dash to higher ground. A nearby house begins to slide down the cliff and they hear a cry for help. Someone is trapped inside!

Just before the house slides into the sea, they rescue Brad Redcliff and his daughter, Melanie. The boys realize they've met Melanie on the mainland -- and where she goes, trouble follows. This time is no exception. By becoming involved with the Redcliffs, they are now targets of a radical political group.

Then Melanie is kidnapped. The radicals send Mr. Redcliff a message -- his daughter will be used as a human sacrifice at noon on Saturday. At the same time, bombs will go off in Honolulu. The political group's plan is to purge the islands of all foreigners.

As police search frantically, a clue in the kidnappers' letter leads Josh and his friends to a sacred waterfall hidden in the jungle where Melanie is being held. Will they reach her before the forbidden ceremony begins? Josh discovers the power of self sacrifice in a daring rescue attempt.
