She has won three San Diego Book Awards. Five of her novels have been BookSense76/IndieBound picks. Bodies of Water was finalist for a Lambda Foundation award. Her thirteenth novel, Keeping Lucy, was published by St. Martin's Press in August 2019.
She teaches creative writing for San Diego Writer's Ink and online for The Writer's Center. She and her husband, Patrick, live in San Diego, CA with their two daughters during the school year and spend their summers at her family's camp on Newark Pond in Vermont.
