Comet in Moominland (paperback)
When Moomintroll learns that a comet will be passing by, he and his friend Sniff travel to the Observatory on the Lonely Mountain to consult the Professors and have many adventures along the way. The adventures of the easygoing Moomintrolls have all the crispness and tart surprise of a lingonberry, thanks to Tove Jansson's light touch, her uncanny sensitivity to universal childhood emotions, and her gift for terse, naturalistic dialogue. This first book in Jansson's series about the Moomins and their friends - small, indescribable Scandinavian creatures - tells of how they try to save themselves from the comet. It's a gentle, offbeat fantasy with fun illustrations. For ages 8-12.
