Yeah, they are pretty light and quick. Like that about them, not every book need to be dense.

As for The Aeronaut's Windlass, I try not to start unfinished series now (with some exceptions). He started Cinder Spire series about 8 years ago, and the second book is releasing in November of this year. I have read his Codex Alera series, and will read this when he finishes it.

He used to be a very consistent writer, releasing a book pretty much every year, let's hope he gets back into the groove.
