Katherine Rundell is the author of Rooftoppers, Cartwheeling in Thunderstorms (a Boston Globe-Horn Book Award winner), The Wolf Wilder, The Explorer, The Good Thieves, and The Zebra's Great Escape. She grew up in Zimbabwe, Brussels, and London, and is currently a Fellow of All Souls College, Oxford. She begins each day with a cartwheel and believes that reading is almost exactly the same as cartwheeling: it turns the world upside down and leaves you breathless. In her spare time, she enjoys walking on tightropes and trespassing on the rooftops of Oxford colleges.
