When Wren was ten, she saw something no child her age should've seen-her mother stabbing a seemingly innocent woman. But that wasn't the worst of it, Wren saw the woman transform into some creature and no one else seemed to notice. Six years later she is still trying to cope with and understand what she saw. Then one night she gets a call from a woman saying she knows about what happened and it suddenly seems like more people know about it than what she thought. But what is "it"? and what exactly did Wren see? And most importantly, why, six years later, do those creatures start coming after her?
