Every night, Milo Reyes falls asleep in Aldercreek. And every night, he wakes up somewhere else.

Two years ago, Milo had one careless argument with his father, and never got the chance to take it back. Since then he has kept himself too busy to think: running until his lungs burn, chasing a state meet, keeping everyone at a distance.

Then the dreams start. Except they aren't dreams. Mareth. Calvorin. Ennurvar. Kelvahr. Worlds with their own skies, their own rules, and people who seem to know more about Milo than he does. And the more he crosses, the clearer it becomes that the journeys have a cost, and that something is watching him.

To protect his home and the people he loves, Milo will have to discover what he really is, and face the goodbye he never finished.

A moving fantasy adventure about grief, love, and the worlds that connect us.
