Black was born in Provo, Utah, and graduated from Brigham Young University, where she earned degrees in history and secondary education. Black met her husband in college and became a full-time mother early on. Their family has lived in Arizona, Massachusetts, Ireland, and northern California. Black enjoyed making up stories when she was a child. After some experimentation with writing as an adult, Black began reading books about writing fiction in preparation for a first novel.
Black's first novel, a futuristic thriller called The Believer, was published by Covenant Communications in January 2005. She "then turned to writing contemporary suspense, and Fool Me Twice was released in 2008, followed by Methods of Madness (2009) and Cold as Ice (2010). Fool Me Twice and Methods of Madness are both Whitney Award winners for Best Mystery/Suspense." Whitney Awards are geared for Latter-day Saint writers. The Whitney Awards honor novels in the following categories: General Fiction, Romance, Suspense/Mystery, Speculative Fiction, Youth Fiction, Historical, Best Novel of the Year, and Best Novel by a New Author. Some consider suspense/mystery novels the most difficult to write.
Jennie Hansen reviewed Cold as Ice for Meridian Magazine:
- "The plotting for this story is a delicate web that moves along at an easy pace, then suddenly rushes to multiple climaxes. It's like an amusement park thrill ride, sending the reader careening off into several directions each fraught with white-knuckle excitement, then leaving the rider at the end both glad it's over and anxious to go again. Black's many fans and those trying something new, will not be disappointed in this thriller." 
Black and her husband have five children.
