Jennifer Killick is the author of Crater Lake, the Alex Sparrow series, and middle-grade sci-fi adventure Mo, Lottie and the Junkers. She regularly visits schools and festivals, and her books have three times been selected for The Reading Agency's Summer Reading Challenge. She lives in Uxbridge, in a house full of children, animals and Lego. When she isn't busy mothering or step-mothering (which isn't often) she loves to read, write and run, as fast as she can.
