From the #1 New York Times bestselling author of Divine Rivals comes a thrilling YA stand-alone fantasy about the unbreakable bond between sisters.

After eight years apart, Evadne can’t wait to see her older sister, Halcyon. But when Halcyon arrives back from the queen’s army a day early, Eva knows something is terribly wrong. Halcyon is on the run, and is being chased by her commander after being charged with murder.

Though Halcyon’s life is spared, her punishment is heavy— five years hard labor, five years imprisonment, and five years serving the house she has wronged. Suspicious of the circumstances, Eva volunteers to take part of Halcyon’s sentence. She’s sent to serve in the commander’s house, where she meets Damon, a handsome mage. Eva must work with Damon on a potentially deadly mission to retrieve a powerful relic that could save the kingdom—and clear her sister’s name.
