This book is a rare find, well deserving of the prestigious Picture Book of the Year award from CBC-NSTA. The science about dragonflies is perfectly integrated into a story in which the remarkable metamorphosis of a dragonfly from a mucky nymph ("Eeeewww," says Eliza) to a beautiful winged creature ("Magnificent!" says Aunt Doris) is a metaphor for the magic of how Eliza, too, is growing up. Teachers will find it useful primarily in an elementary science unit on insects, life cycles and habitats, but also in for language arts lessons in theme, symbolism, and metaphor. The watercolor illustrations are rich, whimsical, and fun. There are two pages of additional science in the back. This is an exceptional example of creative non-fiction writing.
