The Book of Dust (Vol 2): The Secret Commonwealth
by Philip Pullman, 2019

Some cool connections to the first volume in the Book of Dust, La Belle Savage (set 20 years earlier), and the original His Dark Materials trilogy (set ~10 years earlier). However, this book is really just setting up the third volume. The Secret Commonwealth ends with half a dozen story lines hanging uncompleted. Kind of frustrating. I would recommend waiting until the third volume is published before reading this one (which was published in Oct. 2019), so that you’re not left hanging after reading. Unfortunately, there is no current expected release date for the third volume.
