Growing up in a sleepy village untouched by distant wars and political conflicts, it was easy for Thia, Mina and Kiara to forget such horrors existed in the Five Corners. That is until the dead child is found; a child that bears the same strange birthmark that all three sisters possess. A Mark their mother had always told them was unique to the girls. Kiara's suspicions grow as their Inn is soon overrun with outsiders from all walks of life. Strangers, soldiers and Elders who all seem to know more about what is happening than the girls do. After Mina barely survives an attack in the forest, the sisters are faced with a shattering secret their mother has kept from them for years. As danger closes in around them, the sisters are forced from their home and must put their trust in the hands of strangers. With more questions than answers, Kiara finds herself separated from everyone she loves and reliant on an Outlander who has spent too much time in army. She doesn't trust Caedmon but she needs him if she has any hope of being reunited with her sisters and learning what the Mark might mean.
