Having spent the last seven years in an orphanage, Zosia is shocked when someone tells her she’s a sphinx and the last guardian of the sentient library of Supernaturals. The elite academy which houses the powerful library rejects her because she isn’t perfect, but she knows instantly that the library is where she belongs. She ignores the academy’s decree and gathers others around her – four guardians who are just as perfectly imperfect as she is.

But her powers, her ability to shift, and her strength are tied up in the memories she can’t bear to access – memories of torture as a young girl – horrible acts which made her the way she is. When the library is all that stands between two ignorant factions trying to cause a war, it’s up to her and her guardians to prevent it. But first, she has to face her worst fears – including believing in herself.
