When Grace misplaces her toy caterpillar, retracing the steps of her day helps her discover that sometimes you find the most important things where you least expect them.

Cheryl Lock has known since the third grade when she read Robert C. O'Brien's Mrs. Frisby and the Rats of NIMH that writing - and writing children's books, more specifically - would be in her future. Eventually, she moved to Manhattan to follow her writing dreams, working for newspapers, magazines, and websites. Although this is her first children's book, her work has been published in The New York Times, The Washington Post, Forbes, Parents, and loads of other places. She lives in Colorado with her husband and three daughters.
