Her plan? Get over her ex. His job? Keep an eye on his best friend's sister. Their mistake? A dare and a wedding. Hallie needed an escape after being dumped for being "too much" a month before her wedding. Vegas with her best friends seemed perfect, until she wakes up with a ring on her finger and her brother's best friend, in her bed. Firefighter Nate only agreed to watch over Hallie as a favor. He never planned on getting too close, especially to the woman he's secretly wanted for years but considered strictly off-limits. As they scramble to undo their mistake, one wild weekend stretches into a week of undeniable chemistry and unexpected feelings. Maybe their biggest mistake wasn't saying "I do" in Vegas, but rushing to undo it.
