Val has only ever known a Seattle surrounded by the forested Wilds. Like everyone, she's heard whispers about the glittering, ruthless kingdoms and dangerous human-like wildlings deep within. But with a sick guardian and money tight, Val's more than willing to brave the Wilds' depths, carving and selling magic-filled heart gems from its numerous beasts. Until one day she wanders too far and Rune finds her. He's a wildling, more savage and beautiful than any beast, and he has a deal for her: Val will use her unique abilities to help him take the unclaimed high throne of the Wilds. In return, Rune will let her carve the powerful heart gems of his enemies, something there's no shortage of. As Val is thrust into a vicious conflict between Lords, kings, and awakening gods, nothing is as it seems. But both the Wilds and Rune-cruel, kind, broken Rune-hold secrets, and if Val's not careful it might be her heart she loses next.
