BUILD AN ICE RAFT. SAVE THE BEAR. DON'T FREEZE. The Arctic ice is melting, and Nanuk the Polar Bear is in big trouble. He’s stranded, starving, and staring down a deadly 175km swim across the open ocean. Leo and Lily have a plan—but it’s crazy. They aren’t just watching from the sidelines. Using their high-tech drone and a secret substance called Pykrete (super-strong ice made with wood pulp!), the Nature Hackers are on a mission to 3D-print a floating life raft right under the bear’s paws. But the Arctic is unforgiving. With a massive storm approaching, batteries draining fast, and a hungry 600-pound bear getting too close for comfort, the team is running out of time. Can they hack the ice before the storm hits? Or will this rescue mission turn into a frozen disaster? "The Nature Hackers: Operation Polar Bear" is a thrilling STEM graphic novel for kids 8-12 who love engineering, animals, and saving the planet. Scroll up and grab your copy today!
