Lost in the Jungle

Famed inventor Henry "Hank" Witherspoon has gone missing, and it's up to Jack and his brilliant siblings, Ava and Matt, to find him.

At Hank's ransacked lab, the siblings discover clues to the project he's been working on—a new way to generate and store electricity, inspired by the electric eels of the Amazon.

The kids travel deep into the Amazon jungle, following a series of clues Hank has left. Relying on genius, cunning, and new technology, the kids overcome strange creatures, a raging river, and some very clever foes to find their friend and protect his big idea.

Like volumes one and two, LOST IN THE JUNGLE features a glossary of terms and an experiment kids can do at home or at school.
