Stella, Fairy of the Forest by Marie-Louise Gay

In their third adventure, Stella and her little brother cross a field and a creek before spending the day in the forest. Butterflies, snakes, rocks, and sheep provide fuel for Sam's curious-little-brother questions and Stella's big-sister answers as they explore the outdoor world. Gay's watercolors bring the forest alive as the two journey toward their very own fort where Sam resolves to stay forever. Marie-Louise Gay is a multiple-time winner of Canada's Governor General's Literary Award, Canada's Mr. Christie's Book Award, and others. "Gay's illustrations, done primarily in watercolors with a touch of paper collage, are bright and have a whimsical touch." -- School Library Journal
