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.
