The bridge is out. The phones are down. And the most famous mystery writer in the world just disappeared out of a locked room two days before Christmas. Meet Maggie Chase and Ethan Wyatt: She’s the new Queen of the Cozy Mystery. He’s Mr. Big-time Thriller Guy. She hates his guts. He thinks her name is Marcie (no matter how many times she’s told him otherwise.) But when they both accept a cryptic invitation to attend a Christmas house party at the English estate of a reclusive fan, neither is expecting their host to be the most powerful author in the world: Eleanor Ashley, the Duchess of Death herself. That night, the weather turns, and the next morning Eleanor is gone. She vanished from a locked room, and Maggie has to wonder: Is Eleanor in danger? Or is it all some kind of test? Is Ethan the competition? Or is he the only person in that snowbound mansion she can trust?

It’s the middle of the night in the middle of Paris, and a woman just woke up with no memory. She only knows three things for certain: 1) She has a splitting headache. 2) The hottest guy she has (probably) ever seen is standing over her, telling her to run. And oh yeah… 3) People keep trying to kill her. When she sees footage of herself fighting off a dozen men, there’s only one explanation: obviously she’s a spy! Except, according to Mr. Hot Guy, she’s not. She’s a spy’s identical twin sister. Too bad the only person who knows she’s not the woman they’re looking for is this very grouchy, very sexy, very secret agent who (reluctantly) agrees to help her disappear. Which is easier said than done when a criminal organization wants you dead and every intelligence service in the world wants you caught.
