Katherine Rundell is the author of Rooftoppers, Cartwheeling in Thunderstorms (a Boston Globe–Horn Book Award winner), and The Wolf Wilder. 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. Rundell was selected as part of the Hay Festival Aarhus39 earlier in 2017.
