Katherine Applegate lebt mit ihrem Mann, zwei Kindern und einer großen Zahl schrulliger Haustiere in der Nähe von San Francisco. Sie hat schon viele erfolgreiche Bücher veröffentlicht. Für „Der unvergleichliche Ivan“ erhielt sie 2013 die renommierte Newbery Medal. „Der Baum der Wünsche“ landete gleich nach Erscheinen auf der New York Times Bestsellerliste.
Katherine Applegate was born in Michigan, a fact which allows her to pretend she is a hearty Midwesterner, even though she hates the cold. Katherine’s parents, a tolerant sort, allowed her to have many pets growing up, and she worked for a veterinarian in high school. She lived in Michigan, Illinois and Texas before graduating from The University of Texas at Austin with a degree in Aimlessness and a minor in Indecision. Katherine worked as a plant waterer (killed them) and a cocktail waitress (spilled them) before realizing the world would be a safer place if she’d write books instead. Since then, she’s written over 150 books for children and young adults, many in collaboration with her husband, Michael Grant. ANIMORPHS (Scholastic), their long-running series, sold over 35 million copies worldwide. They don’t collaborate much anymore, because they would like to remain married. Katherine lives near San Francisco with her husband, two children, and an array of neurotic pets.
