Born in Cleveland, Ohio and raised in San Francisco, she earned a degree in communications from San Francisco State University. Zarr grew up as part of a Jesus Movement church. Her first three manuscripts were never published, but after winning the Utah Arts Council prize for best unpublished young adult novel of 2003,[3] she was able to find an agent who successfully sold Story of a Girl as the first of a two-book deal, to Little, Brown Books for Young Readers.[4]
Inspired by the kidnapping of Elizabeth Smart and Zarr's Christian roots, her third book, Once Was Lost (also published as What We Lost) addresses issues of faith, identity and home. The original title comes from the hymnAmazing Grace written by John Newton.[5] While the characters are Christian, the book was published for a mainstream audience and neither promotes nor criticizes organized religion.
In 2013, Zarr joined the faculty of Lesley University’s Low-Residency Master of Fine Arts in Creative Writing program.[8]
From 2012-2015; 2020-present Zarr hosted and produced the podcast This Creative Life. It featured Zarr in conversation with other writers. She has self-published a companion book to the podcast.
With her 2017 novel, Gem & Dixie (loosely based on some of her early life experiences[9][10]), Zarr moved to the HarperCollins imprint Balzer + Bray, and has another book slated with them for 2018.
