Beth McMullen graduated from Boston University with a degree in English Literature. After landing a gig with Reader's Digest, she eventually realized she'd rather write books than condense them. She relocated to San Francisco, California, and worked in Silicon Valley to pay the bills, trying to do as much writing and traveling as possible. Finally, after getting married, she and her husband decided to take one year and see as much of the world as they could before they ran out of money. It's a big world.

Beth currently divides her time between writing and taking care of her two children, Max, 5, and Katie, 3. She holds an MLS from Long Island University and lives with her husband and children in Davis, California.

After falling in love and making a quick exit from her nine-year career in the USAWMD (United States Agency for Weapons of Mass Destruction), ex-spy Sally Sin does her best to become Lucy Hamilton, a stay-at-home mom in San Francisco. No one, not even her adoring husband Will, knows about her secret agent escapades -- chasing no-good masterminds through perilous jungles, escaping evil assassins, and playing dangerous games of cat and mouse with her old nemesis, Ian Blackford, a notorious and dashing illegal arms dealer. In her new life as Lucy Hamilton, she squeezes inside forts crafted from couch cushions by her three-year-old son Theo, makes organic applesauce, and frequents the zoo. But sometimes her well-honed spy reflexes refuse to lay low. She can't help breaking into her own house to check on the babysitter or stop herself from tossing the yoga instructor who gets on her nerves. And when Ian Blackford, who is supposed to be dead, once again starts causing trouble for the USAWMD, the agency becomes desperate to get Sally back on the job. How can Sally or Lucy or whatever her name is save the planet while at the same time keeping her own family's world from spinning out of control? Every bit as much fun as a spy-mom thriller ought to be, Original Sin is a fast-paced adventure story for mothers and spies, and anyone who has ever dreamed about being either.
