Author Bio

Mary is the author of the Dori O. Paranormal Mystery series. Lost in the Light was nominated for the Daphne du Maurier Award in Paranormal Mystery and winner of the Orange County Chapter of RWA’s Book Cover contest.

Cosmopolitan magazine selected her debut novel, Hot Tamara as the Red Hot Read of April 2005.

Latina magazine called Mary “an author to look out for” and selected In Between Men and Names I Call My Sister for the Top 10 Summers Reads in July 2009. OC Metro magazine named Mary one of the hottest 25 people in the O.C. . She was profiled in Romantic Times Magazine,  Orange County Register, Coast, The Arizona Republic, San Diego Magazine and San Diego Union-Tribune.

Mary grew up in a haunted house in National City, CA. She cries every time she sees the movies, The Ghost and Mrs. Muir and Casablanca, and feels that Joan Collins is by far the preeminent TV villain (which is why Joan plays such a pivotal role in the novel, In Between Men).

A graduate of USC, Mary lives in So Cal wine country with her family.
