In the first volume of a proposed duology, Valen, the rebellious scion of a dynasty of pureblood cartographers and diviners, has spent years denying his heritage, until he nearly ends up dead, addicted to a spell that converts pain to pleasure and possessing only a stolen book of maps, a mystical volume that could hide the secret to the doom of the entire world. Original.

As the land of Navronne sinks deeper into civil war and perilous winter, everyone wants to get their hands on the rebellious sorcerer Valen -a murderous priestess, a prince who steals dead men's eyes, and even the Danae guardians, whose magic nurtures the earth and whose attention could prove the most costly of all. Addicted to an enchantment that turns pain into pleasure -and bound by oaths he refuses to abandon- Valen risks body and soul to rescue one child, seek justice for another, and bring the dying land its rightful king. Yet no one is who they seem, and Valen's search for healing grace leads him from Harrower dungeons to alien shores. Only at the heart of the world does he discover the glorious, terrible price of the land's redemption-and his own.
