The library of the unwritten

Many years ago, Claire was named head librarian of the Unwritten Wing - a neutral space in Hell where all the stories unfinished by their authors reside. When a hero escapes from his book and goes in search of its author, Claire must track and capture him with the help of former muse and current assistant Brevity and the nervous and sweet demon Leto. But what should have been a simple retrieval goes horrifyingly wrong when the terrifying angel Ramiel attacks them, convinced that they hold the Devil's Bible.
