Worldsoul

"What if being a librarian was the most dangerous job in the world? Worldsoul, a great city that forms a nexus point between Earth and the many dimensions known as the Liminality, is a place where old stories gather, where forgotten legends come to fade and die - or to flourish and rise again. Until recently, Worldsoul has been governed by the Skein, but they have gone missing and no one knows why. Mercy Fane and her fellow Librarians are doing their best to maintain the Library, but things keep breaking out of ancient texts and legends are escaping into the city. She turns to Shadow, an alchemist, for aid, but Shadow has a perilous quest of her own to undertake."
