Thirty-seven years after the Republic’s fall, the five clans and Kingsland battle for control of the last untainted land. Isadora, an eighteen-year-old healer, saves lives on the battlefield until she’s struck by a poisoned arrow. To her shock, Tristan—a deadly Kingsland assassin—saves her with rare magic, binding their lives together. Their forced connection lets him glimpse her memories, threatening her people’s survival, but it also gives her access to his. Torn between duty and an undeniable pull toward her enemy, Isadora must decide whether to risk her heart while plotting to destroy Tristan and the people he serves.
