When a contagious, deadly virus appears, Doc Dee and Invisible Six must find its source. The mission takes them into the Rift, a lawless section of the Amazon rain forest.

Can Doc Dee and I-6 locate patient zero and stop a pandemic from happening? Aligned to Common Core Standards and correlated to state standards. Claw is an imprint of Magic Wagon, a division of ABDO.
