For six years, Valeria Evernight has survived in a world left empty by the Vanishing, tirelessly preparing a ritual to find her lost mother. But when she finally completes it, the spell doesn’t bring her mother back; it summons Caelum, a boy from another world who is just as lost as she is. Worse still, he doesn’t even speak her language.

As they struggle to communicate, a strange companionship begins to form between the two: one that may reveal they share far more than just their loneliness.
