The Keeper's Six

It's been a year since Esther set foot in the Beyond, the alien landscape stretching between worlds, crossing boundaries of space and time. She and her magical traveling party―her Hex―haven't spoken since the Concilium banned them from the Beyond for a decade. But when she wakes in the middle of the night to her grown son's cry for help, the members of her Hex are the only ones she can trust to help her bring him back from wherever he has been taken.

There are terrors that dwell in the space between worlds.
