What does it mean to be alone? In a world without consequences, what would you do? In the blink of an eye, three people in different parts of the globe find themselves removed from the constraints of society when the rest of humanity vanishes. Afforded a wider perspective on their lives, each character is forced to examine both their place in the world and the pivotal moments on which their very existence may depend. Ranging from the streets of London and Los Angeles to a demon-haunted forest in the shadow of Mount Fuji, Celeste is a story about the choices we make and the courage it takes to make them.
