It’s weird. I don’t hate it, but the author spends way too much time dealing with “timeline forks” (I’ll call it that to avoid spoilers) in a limited setting with a lot of reiteration and lack of any real plot advancement or character development. It’s not awful, I don’t hate it, but it’s a completely different book than the first or second. If you liked the first and didn’t care for the second you probably won’t like this one at all.

I'm not the Op, but I found book 3 even more of a let-down than book 2. Just felt a bit more contrived, even though it did add some valuable contributions to the universe, and I'll read book 4 when it comes out.
