Kimberley Griffiths Little was born in the vibrant city of San Francisco and now resides in New Mexico with her husband and three sons, near the banks of the Rio Grande. She is an award-winning author known for her captivating middle grade and young adult novels such as When the Butterflies Came, The Last Snake Runner, The Healing Spell, and Circle of Secrets.
