Sherry Monahan began her writing career when she combined her passion for food, travel, and history to pen her first book, Taste of Tombstone, in 1998. That same passion landed her a monthly magazine column in 2009 when she began writing her food column in True West entitled, "Frontier Fare". She also enjoys researching the genealogy of food and spirits. Her work has followed some interesting women on the frontier. Her Mrs. Earp book details the lives of the women who called themselves "Mrs. Earp". In Wicked West, she looks at all the vices on the frontier including prostitution, drinking, drugs, and gambling.

She is a past president of Western Writers of America (2014-2016) and holds memberships in the James Beard Foundation, the Author's Guild, Women Writing the West, Single Action Shooting Society, and the Wild West History Association. Sherry is also a member of the Association of Professional Genealogists. Sherry is one of the original members of the Most Intrepid Western Author Posse. She and her fellow posse members were sworn in as honorary Dodge City marshals during one of their "rides."
