Maria Gianferrari has always loved trees. She has climbed fig trees in Italy, stood under stately coastal redwoods and twisted Torrey pines, and marveled at mitten-shaped sassafras leaves, colorful coral trees, and sawtooth oak acorn nests. She lives with her family in a house encircled by trees, one of which is a spruce planted in memory of her beloved dog, Becca. Be a Tree! is her first book with Abrams. ; Felicita Sala is the self-taught illustrator of several picture books, including Be a Tree! by Maria Gianferrari and The Hideout by Susanna Mattiangeli, as well as her own book of recipes for children, What’s Cooking at 10 Garden Street? She grew up between Italy and Australia and now lives in Rome, Italy, with her family.
