Helen Foster James is the author of a dozen books for children, including Grandma Loves You!, Auntie Loves You!, and Santa's Christmas Train. When she's not writing and rhyming words, she enjoys riding trains with her husband, traveling, reading, and hiking with her friends in the mountains where she is a naturalist interpreter. She lives in San Diego, California. Estelle Corke began her career in advertising, magazine, and package illustration, but her first love is children's book illustration. She's a traditional artist who chooses to use real paints in a bright and bold way, injecting quirkiness and humour whenever she can. She lives in the United Kingdom.
