Scholastic Harley Hitch and the Iron Forest

Welcome to Inventia, where technology blooms – literally! Trouble Seems to follow Harley Hitch everywhere. That might mean explosions at school, runaway robots or a giant slug! Deep in the Iron Forest, Harley and her new friend, Cosmo, notice an unusual fungus. The forest is special – its plants grow the mechanical parts that everyone needs. When the fungus starts spreading fast, all of Inventia could fall apart! What – or who – is causing this strange growth? Harley Hitch is on the case!
