WOLF ISLAND Celia Godkin. Markham, ON: Fitzhenry & Whiteside, 1989. 38pp., cloth, $18.95. ISBN 0-88902-753-6. CIP. Subject Heading: Wolves-Juvenile fiction. Kindergarten-grade 6 / Ages 5-11 Reviewed by Adele M. Fasick. Volume 18 Number 1 1990 January Based on an actual event, this book tells what happened to an island in northern Ontario when a family of wolves left the island for the mainland. Life was easy at first and deer flourished and multiplied, eating so much food that rabbits had less to eat and the foxes, which depended on rabbits for food, had even less. When a hard winter came, the animals suffered from the food shortage. Even the deer were hungry and began to nibble at trees, which then died. As the weather grew colder, ice formed a bridge to the mainland and the wolves returned. They ate the weaker deer and brought the population back into balance and enabled other animals to survive. Rarely has the working of an ecosystem been demonstrated in such a straightforward and dramatic way. Young children will be able to understand the story, and older children will find much to think about and discuss. Celia Godkin does not waste a word and her lovely full-colour illustrations make this a memorable book, which should be in every school and public library. Adele M.
