The unbound - Victoria Schwab

Imagine a place where the dead rest on shelves like books. Each body has a story to tell, a life seen in pictures that only Librarians can read. The dead are called Histories, and the vast realm in which they rest is the Archive. Mackenzie Bishop is still recovering from having almost lost her life to a violent History. But moving on is proving a difficult task when all she dreams of is that fateful day. And when people begin disappearing, all lines lead back to her. Mackenzie fears a set-up and the race is on to prove it.
