From the description:
"Laying hands upon the injured and dying, Avry of Kazan absorbs their wounds and diseases into herself. But rather than being honored for her skills, she is hunted. Healers like Avry are accused of spreading the plague that has decimated the Fifteen Realms, leaving the survivors in a state of chaos.
Stressed and tired from hiding, Avry is abducted by a band of rogues who, shockingly, value her gift above the golden bounty offered for her capture. Their leader, an enigmatic captor-protector with powers of his own, is unequivocal in his demands: Avry must heal a plague-stricken prince—leader of a campaign against her people. As they traverse the daunting Nine Mountains, beset by mercenaries and magical dangers, Avry must decide who is worth healing and what is worth dying for. Because the price of peace may well be her life."
