But Stella's father has never been one to play by the rules. Leaving behind her pet polar bear, Gruff, and beloved unicorn, Magic, Stella and Felix set off on an expedition to the snowy Icelands. There, Stella plans to prove herself as a junior explorer, worthy of membership in the Polar Bear Explorers' Club. So when Stella and three other junior explorers are separated from the rest of their expedition, she has the perfect opportunity. Can they explore the frozen wilderness and live to tell the tale?"--
