You never stop worrying about your kids, even when they're adults.
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.
Esther will have to risk everything to find him. Undercover and hidden from the Concilium, she and her Hex will be tested by false dragon lords, a darkness so dense it can suffocate, and the bones of an old crime come back to haunt her.
There are terrors that dwell in the space between worlds.
Includes Servant Mage, a bonus novella from author Kate Elliot, narrated by Kate Rudd.
