"I can’t remember the last time I smiled so much while reading a book.”—Annabel Monaghan, author of Nora Goes Off Script and Same Time Next Summer

An undercover CIA agent is sent home for Christmas to investigate her sister's criminal fiancé but the last thing she expects is to fall in love with his bodyguard along the way.

It’s been a long time since Sydney Swift has gone home. An unrelentingly successful CIA field officer, she has spent the last three years pretending to be someone—anyone—other than herself.

But this year, the festive season is coming with some added surprises. Sydney’s beloved little sister has just announced that she’s engaged to Johnny Jones, the heir of an organized crime dynasty. With her built-in cover and her best-in-class reputation, Sydney is approached by the FBI as their way to infiltrate the Jones family at last.

Sydney has until Christmas to gather enough evidence on Johnny to take him down before he pulls off his most dangerous heist yet, all without losing her sister forever. But she hasn’t counted on the challenge of pulling this off right under her family’s nose or the complications of a romantic entanglement with Johnny’s handsome friend and bodyguard, Nick. Sydney always gets her man—but this time love is a target she can’t afford to miss.
