Lily hates holidays. They’re loud, unpredictable, and involve too many social dynamics. She’s been there, peopled hard, and has the memory of her ex dry-humping his assistant on the Fourth of July to prove it.Now her life’s summarized by three things: tea, cats, code. Specifically the code for her holiday app, Calm the Carols, designed to reduce stress and social fumbles while offering hacks for the holiday ho-ho-horrors neurodivergent people like her face.Start-ups need money, and Lily needs rent. Conveniently, Rowland needs a place to stay. Inconveniently, he's everything Lily's not: he loses his keys, writes checks, makes friends with everyone, and worst of all, loves the holidays—enough to buy a rundown building for a year-round holiday-themed café.To win over investors, they launch a social media campaign. Lily demos her app while her new roommate shows off themed drinks as they tackle a holiday bucket list. But somewhere between four-part caroling and being accepted by Rowland’s family, Lily develops feelings that she can’t classify as a user error.If the holidays don’t kill her first, fa-la-la-la-falling for her roommate just might.For readers who love:He falls firstRoommates to loversForced proximityBlack cat x Golden RetrieverWomen in STEMFMC with AutismGentle MMCSlow burn
