You've Got Mail meets The Hating Game! Vying for a promotion against a bitter rival as the only female data analyst for a professional baseball team, Emmy finds solace in the text-flirting relationship that started as a wrong number exchange--unaware that the man she's texting is the one she's fighting for the promotion.

Emmy Jameson lives by three rules: no dating, no sharing personal news at work, and baseball above everything. As the only female data analyst for a professional baseball team, Emmy is constantly trying to prove herself.

Especially when she's put up for a senior analyst position against her arrogant, infuriating coworker Gabe Olson. Sure, he's gorgeous and smart and he was a baseball star in college who knows the sport inside and out, but so does Emmy. She is not going to lose to him again. There will be no distractions this summer. Not even her sister's pending destination wedding in Mexico for which she needs to find a plus one.

But then she receives a text from an unknown number with a simple message: "Last night was fun." When she strikes up a conversation with the mystery texter, they realize that he was given a fake phone number after a bad date that just so happened to be Emmy's. Despite her rules, Emmy can't deny the instant connection she feels and soon finds herself falling for the stranger on the other side of the screen...and inviting him to her sister's wedding.

Emmy's world turns upside down when her mystery man turns out to be none other than Gabe Olson. They are left having to travel to the wedding together while trying to sort out which version of their relationship is real: their in-person rivalry or the deep connection they found in their messages.
