"You are a country."
Those words have been the guiding force behind Queen Mona's every move since she was a little girl-the idea that all her actions and desires were, first and foremost, decided based on what was best for Lumen Lake. It had kept her alive after the Alcoran invasion, it had driven her to retake her country, and now it is the steely resolve she needs to finally confront the despotic Seventh King, Celeno.
But when her diplomatic mission finds herself on the run through the swamps of Cyprien-accompanied by the unlikeliest group of companions-Mona discovers that while she is her country, she is also someone who has been sheltered by principles and bound by past mistakes. Now she must struggle to reshape her view of the world and face intimate new truths-not only for the good of her country, but for herself, as well.
