The Wedding Party (The Wedding Date, #3) by Jasmine Guillory

Maddie and Theo have two things in common: 1. Alexa is their best friend 2. They hate each other After an “Oops, we made a mistake” kiss, neither one can stop thinking about the other. With Alexa’s wedding rapidly approaching, Maddie and Theo both share bridal party responsibilities that require more interaction with each other than they’re comfortable with. Underneath the sharp barbs they toss at each other is a simmering attraction that won’t fade. It builds until they find themselves sneaking off together to release some tension when Alexa isn’t looking. But as with any engagement with a nemesis, there are unspoken rules that must be abided by. First and foremost, don’t fall in love.
