Things heat up at Hills Village Middle School when Rafe gets an invitation from Dr. Daria Deerwin to join a research study on polar bears. How many times in life do you get a chance to come face-to-face with a real polar bear in the wild? Rafe is ready to find out! Alaska is pinkie-freezing, hair-freezing, snot-freezing cold, but Rafe might be headed for a meltdown. He's spending every waking moment with Penelope, who he definitely has a crush on, and a polar bear Dr. Deerwin is tracking goes missing...with poachers on the tundra. It's up to Rafe, Penelope, and their new friends to save the day in Rafe's coolest adventure yet.
