Rom-com obsessed but perpetually single Avery Blackwell abandons her plans to attend Columbia in favor of spending her freshman year at her recently deceased mother’s alma mater in a seaside town in England. On the train, Avery makes a deal straight out of one of her beloved romance books with a charming local girl named Charlie: if Avery will pretend to be her girlfriend to make her ex jealous, Charlie will help Avery solve the scavenger hunt her artistic, free-spirited mother left behind on campus decades ago. As their quest takes them all over Brighton, Avery finally starts to connect with the mother she always loved but never really understood. Before long, pretending to be Charlie’s girlfriend starts to feel like more than just an illusion. But when long-hidden secrets come to light, Avery grapples with an uncertain future and whether or not love is worth the risk.
