Beverly 'Bev' Kitagawa struggles to connect with people around her. For the last decade, her vow to write a novel about the boy she romantically spurned in college - as an apology to him - has given her purpose. But with the ten-year anniversary approaching and little to show for it, Bev is beginning to feel hopeless. The only constant in her life is her job at the local cereal bar, Cows. Then, one month before her twenty-eighth birthday, she takes a sip of milk from a customer's bowl and temporarily slips into an alternate timeline of her life. There, she has everything that seems impossible in her actual existence. A bond with a customer she's crushed on from afar. The writing career she's always dreamed of. So she tries it again. And again. As she races to finish writing her real-life book, Bev dives deeper into the milkiverse. Is the next sip the key to the success, acceptance, forgiveness and love she's spent a decade searching for?
