I went into this book thinking that this was a trilogy, and I was a little worried how they were going to wrap everything up. Thankfully, there's one more book left in the series.
Where the last one was more 80s sci-fi, this one felt like it was a nice blend between the horror of the first novel and all the alien goodness of the second. This one, more than the previous two, really felt like Stranger Things, what with Rae, Caden, and Vivienne venturing into the Other Place on a rescue mission, but not in a derivative way. It doesn't feel like a repackaged Stranger Things fanfiction nor does it feel like a straight ripoff; the similarities are there, but it's very much it's own thing.
Reckoning is a much more focused novel than Infestation. I mean this in the nicest way possible, but Infestation really was all about laying the ground work for this book. (And I say this as someone who liked Infestation.) A lot of new ideas where being thrown out, and there was a tonal shift from paranormal creatures from another realm stealing children's eyes to giant killer alien bugs. Here, the two blend together better, the plot lines are pared down and we can see that everything that has happened isn't simply a series of wild events that happen in this zany town, but it's all interconnected. There are several plot twists, and while as an adult I could guess most of them--I'm not going to lie though, there was a red herring that I totally fell for--they're still exciting. Each one had me going, "YES" because the story is just getting crazier and crazier.
I cannot stress enough how fantastic this series is, and not just in a "Oh yeah, kids will love this" way. I'm in my 30s and I LOVE this series. I am constantly telling everyone I know about these books--I horrify my coworkers by giving them updates on what's happening, eliciting cries of, "And this is for children??" every time--and I always have a copy on hand when I'm doing a book talk.
September cannot come soon enough.
