Liz Williams, author of the Inspector Chen books, just signed a three-book deal with Prime Books, for her Worldsoul Trilogy. It has the best tagline I've heard in ages: "What if being a librarian was the most dangerous job in the world?" And here's the blurb, from Prime founder/editor Sean Wallace's blog:

The first book focuses on Worldsoul, a great city that forms a nexus point between Earth and the many dimensions known as the Liminality: a place where old stories gather, where forgotten legends come to fade and die - or to flourish and rise again . . .

Adds Williams, on her own blog:

It's about a stolen library, an unstable monorail, several renegade sphinxes and much else besides.
