Stella Starflake Pearl lives with her explorer father, Felix, alongside her pet polar bear, Gruff, a menagerie of pygmy dinosaurs and her trusty unicorn, Magic. Ever since Stella was a small child, Felix has gone away on expeditions to faraway lands, and returned with fascinating curiosities and incredible tales. Stella has always enjoyed his stories, but now she’s ready to start having a few adventures of her own.
She finally convinces Felix to take her with him on his next journey, and the expedition duly embarks with its supplies of wolves, sleds, unicorns, iced gems and expedition-strength moustache wax. But once their ship reaches the snowy Icelands, Stella and the other three junior explorers find themselves separated from the rest of their expedition.
Setting out together into the frozen unknown, they must keep all their wits about them if they are to come face-to-face with frost fairies, snow queens, outlaw hideouts, carnivorous cabbages – and live to tell the tale.
