I've just spent two months reading all six books of the Sundering storyline and I'm finally finished.
It was a mixed bag and I don't, generally, read gaming fiction.
The first two books are excellent, the third was so-so but I'll read Evans' next novel, the fourth (by Richard Lee Byers, a favorite author of mine) was okay, the fifth and sixth were mostly worth reading.
I will say that I am not a fan of Ed Greenwood's writing, but this latest book, especially the ending, made me decide to try out his next Forgotten Realms book.
Overall, I recommend them. I was hoping for a few more answers, but this was a reset and it's done now.
Reading the book series and casually playing the Neverwinter MMO is just an example of how happy I am with DnD 5E and how much I want to participate in the brand.
I know that's not for everyone, but it's working for me.
As an aside, I'm surprised that more positive coverage hasn't occurred from the authors using gay, lesbian, and bi-sexual characters in the series. While I haven't read a ton of DnD books, I found the presence of such characters well-handled and positive examples.
