In a story dotted with Inuktitut words, Johnston (Those Who Run in the Sky) introduces Nalvana, a girl who wears a blanket cape and an old pair of snowmobiling goggles-it-s her superhero costume. Newcomer Mack draws Nalvana with a button nose, dots for eyes, and an excited smile; her pet husky galumphs along beside her bicycle. The Arctic village they cycle through is lined with small, wooden houses, the landscape rocky and treeless. Nalvana longs to have a superpower, the sort she readily sees in her friends: Davidee -can run faster than a Ski-Doo,- Maata can swing high, and Joanasie can make an inuksuk out of stone and an iglu from snow. Nalvana praises and encourages them all. It-s Nalvana-s mother who identifies her daughter-s talent: -Your superpower is making people feel good about themselves.- Readers who struggle with doubts about their own abilities will be reassured while simultaneously recognizing that children who live in distant places have problems not so different from their own. A glossary is included. Ages 3-5. (Aug.)
