The biggest weakness of this book is that it feels like it was mostly written to set things up for the new "High Republic" era of Star Wars.

There were far too many characters within a relatively short book. For the entire first act of the book, I felt very confused, and it wasn't until the introduction to the Nihil, that the book became more interesting.

For me, the Nihil really were the stars of the book and there were too many Jedi who had uninteresting plots. I doubt that I'll even remember what any of the Jedi did in the book come next week.
