Really enjoying this series, too. (wanderinginn.com) Amazing amount of output from the author, and while there's no way you can enjoy every plot thread (I just don't care for Flos), it's amazing how often I get excited when a new chapter starts from a new perspective.
Personally, I'm also working on "When the Clock Broke" https://www.goodreads.com/book/show/195790601-when-the-clock-broke and "This America of Ours" https://www.goodreads.com/book/show/58311951-this-america-of-ours
Both are interesting reads, but "America" is definitely largely lighter material ..(wild, given it's about McCarthy-era politics)
Those are two non-fiction books about American politics. Very different from Innworld...
