But when Halcyon unexpectedly appears a day early, Eva knows something is wrong. Halcyon has charged with a heinous crime, and though her life is spared, she is sentenced to 15 years. Suspicious of the charges, brought forth by Halcyon’s army commander, as well as the details of the crime, Eva volunteers to take part of her sister’s sentence. If there is a way to absolve Halcyon, she’ll find it. But as the sisters begin their sentences, they quickly learn that there are fates worse than death.
