This is a wildly imaginative speculative fiction story. Carolyn is a “librarian” in a library that contains all the secrets of the universe. However, she is like no ordinary librarian; her agenda is complex and difficult to describe. The story is complicated to enter and impossible to predict. So, imagine gods and monsters, much bloody violence but occasional hilarious sections. Reading this book reminded me of Neil Gaiman’s American Gods. In short, a very original epic fantasy about cruelty that is also a thriller.
