Mace attended LDS Business College and Utah State University. She wrote her first short story while a student at USU. She wrote four novels before Spare Change was published. A young woman whose New Year's resolution has far reaching results is the topic of Spare Change.

In 2009 her Young Adult novel, My Fairy Grandmother was published. It is the story of a grandmother who just happens to be a fairy. She passes along her life history along to her granddaughter and daughter-in-law.

Her holiday novel Santa Maybe also appeared in 2009. The novel explores what happens when Santa leaves a handsome man for a young woman at her request. Santa Maybe was nominated for a 2009 Whitney Award. Mace's Spare Change won a 2008 Whitney Award. The Whitney Awards are named in honor of O.F. Whitney whose discourse "Home Literature" talked about the Miltons and Shakespeares who would eventually come out of the Mormon faith. The Whitney Awards honor fiction by LDS authors. They are sponsored and endorsed by LDStorymakers, a guild for LDS writers.

Mace uses notebooks to write portions of her drafts. What she does not use, she crosses out. Mace likes to attach stickers and fortunes from fortune cookies to her pages to encourage her as she writes.

Mace works in the medical field and does her writing at night and on the weekends. She lives in Sandy, Utah.
