She's an army sergeant who sticks to the rules. He's a womanizer who loves breaking the rules. She hates him and he sorta can't stand her. By some freak accident (or was it?) they swap bodies, a la Freaky Friday. What can possibly go wrong? When Army Sergeant Keira Holtslander, an orderly and rule-loving intelligence analyst, is reassigned to the Pentagon for a special assignment, she agrees to room with her brother's best friend, Dillan. But there's a problem. Several, in fact. He's sarcastic, egotistical, full of himself, extremely attractive, and a womanizer. Within a matter of days, her life is chaos. She didn't like him when they met nine years ago, and her opinion isn't likely to change now. Businessman Dillan Pope has learned to use his looks, charm, and sexual skills to his advantage. Women easily tumble into his bed and business deals come about effortlessly. But when his best friend's little sister moves in, he knows he's in trouble. She's rather hostile toward him, which takes him by surprise. Not even his patented smile works on her. But maybe that's why Keira, aka Sergeant Prim and Proper, has always been the one girl he hasn't been able to forget since their first meeting, nine years ago. When a meddling barista puts a charm on the roommates, causing them to swap bodies, they have less than one week to work together and undo the switch, or live forever in the others body. But first, they must get along. Maybe there's a reason they hated each other. And admitting the feelings that lay hidden may be the only way to undo the switch.
