The Midnight Library meets Everything Everywhere All at Once in this unputdownable adventure about a woman whose fantasies of escaping her humdrum life inadvertently disrupt the fabric of reality.

Esme Good is an unremarkable young woman working a dead-end job in an unremarkable city. Her only escape is The Elsewheres: tiny potions that allow you to disappear for fifteen minutes into alternate versions of yourself. Sadly, these only confirm her suspicion that she is, in a cosmic sense, living her worst life.
 
Then, after a workplace incident that could have happened to anyone, Esme unintentionally becomes the most important person in this—or perhaps any—universe. We don't have time to get into exactly why this is, but to remedy it, Esme must find an uncharted land and fulfil a prophecy that has been on hold since the dawn of time.
 
She has spent her whole life trying not to become a main character. Now, a lot of things are about to happen to her: in fact, everything, and so much.
