Erin Kraan is the illustrator of Mouse Calls by Anne Marie Pace, Nerdycorn by Andrew Root, and Something's Wrong! by Jory John. She grew up in a family of woodworkers, sewers, and painters, crafters who greatly influenced her chosen illustration medium, woodcut printing. She loves the process of carving her characters into the wood and seeing how their quirky and whimsical identities come to life through the ink in the prints. She lives in Vancouver, Canada, and adores big mugs of milky coffee, cozy socks, chickadees, smelly candles, and the color green.
