Raya is a lost soul, going through the motions of life without a dream of her own. One night, on her subway ride home, Raya's thoughts wander too far. She wakes on the Elsewhere Express, a magical train that offers its passengers a sense of purpose, peace, and belonging. The train's endless journey is a chance for Raya to reimagine her life - but only if she finds her compartment before time runs out. On board, Raya meets a charming, handsome artist named Q and together they race to find their place on the train, through a boarding car carpeted in meadow grass and along a dining carriage where passengers picnic on lilypads. But a mysterious stowaway has boarded with them, and with it a dark, malignant magic that threatens to destroy the train and everything in it. The closer Raya comes to uncovering the stowaway's identity, the nearer she draws to the ultimate question: what is her life's true purpose?
