Pepper is a swim team captain, chronic overachiever, and all-around perfectionist. Her family may be falling apart, but their massive fast-food chain is booming-- thanks to Pepper, who is secretly running Big League Burger's massive Twitter account. Jack is a class clown and a constant thorn in Pepper's side. He works at his family's deli. His relationship with the business that holds his future might be love/hate, but when Big League Burger steals his grandma's iconic grilled cheese recipe, he'll do whatever it takes to take them down, one tweet at a time. While Pepper and Jack's spat turns into a viral Twitter war-- publicly duking it out with snarky memes and retweet battles-- they're also falling for each other on an anonymous chat app Jack built. -- adapted from jacket.
