The Wedding Date by Jasmine Guillory ($8) starts when Alexa and Drew find themselves stuck in an lift together and she agrees to be his date and fake girlfriend for his ex's wedding the next day. Turns out, they have so much fun together that they decide to continue a casual fling after their whirlwind weekend, even if it means going long-distance.
This story reminds me a lot of the 2010 film Going the Distance (RIP Drew Barrymore and Justin Long), as Alexa and Drew spend steamy weekends together in between navigating their respective jobs in different cities. In fact, I can already see a montage of their weekend dates playing out on screen! This book is unrelated to the 2005 film of the same name, which, if you haven't seen, I also recommend!
