The most recent book is actually The Secretist (Yes, Keeper, the name is stupid), which is an ebook available on various platforms as long as you live in the right part of the world and have access to a credit card (Yes, I'm still angry about this). It deals with Jace on Ravnica during the current events of Return to Ravnica (as far as I can tell) and is written by Creative's very own Doug Beyer.
