Hadley Hartwell is the pen name of Sarah Skilton, whose traditionally published novels have been published in seven territories and translated into six languages. She was a 2019 Edgar Awards judge in the best juvenile mystery category. Her love of "Murder, She Wrote," cozy cat mysteries, and the Enneagram led her to create the Purrs & Personality Types mysteries, a series straight from her Type Four heart. She lives in a suburb of Los Angeles with her magician husband and teenage son. When she's not writing or parenting, Hadley volunteers at a cat cafe.
