Paper and fire - Rachel Caine

Now, barred from his goal of becoming a Scholar, he's determined to make his career as a High Garda soldier a success. But news that a friend may be imprisoned and suffering brings Jess back with his old companions, and to a common cause: rescue.Failure means death. Success means that their uneasy truce with the Archivist becomes open war.But they have a secret that may shake the very foundations of the Library ... if they dare to use it.Paper and Fire takes us on a breathless journey from battlefields to ancient tombs, from Alexandria to Rome, and to the edge of a world that must change to survive.
