To break out of a 24-hour time loop, all Jack needs is for Gemma to fall in love with him in a single day. All Gemma needs is to remember him first . . . Gemma Peters is doing fine. She's making a name for herself in the L.A. music biz as a radio producer. She's got a ride-or-die best friend in Lila, and she gets to come home to Rex, her loving Labrador, every night. But ever since her rock star ex-boyfriend used her to get a record deal from her rock legend dad, she's made a "no musicians" rule when it comes to dating that's becoming more like a "no dating" rule, period. So, when Gemma crashes (literally) into Jack one Thursday morning, at first she feels like fate might finally be doing her a favor. After all this guy is cute and, wait, is she imagining it, or is he staring a little too deeply into her eyes? And how does he know her name? Even harder to explain is the funny feeling of dej vu she gets every time she looks at him. It's not at all like Gemma to kiss a man and forget him completely, so then how can she explain the dreamlike memory of his lips on hers? The truth is this is no ordinary Thursday. Not for them. In fact, they've lived this day over and over for months. And while Gemma has been totally oblivious to the time loop, Jack has been agonizingly aware of every single iteration. Luckily, Jack has a theory to bring his own personal Groundhog Day to an end. And it's simple. Before the day is over, he just has to get Gemma to fall in love with him.
