Ender's Shadow was fine, if not great. This book is bad and should feel wrong. Orson Scott Card decides to get weirdly preachy and weird moments, he keeps emphasizing how nothing but children matter, he's incredibly offensive to people with genetic disorders (cough ME), and he seriously says at the end that Guns, Germs, and Steel laid the ground rules for him. And everyone should read it. Makes sense. Oh, and he can't write women. Spoilers everywhere.
The Ghost Brigades wasn't what I was expecting, but that was absolutely fine. I certainly wasn't thinking John Scalzi would ditch most of the humor that made Old Man's War what it was. However, it wasn't a problem. The Ghost Brigades still stands up well, even if I didn't feel it was as good as the first book.
I love John Scalzi. I read Fuzzy Nation in the past year as well, and there's just something about his writing that works for me. I'd read Old Man's War in the past, but this wasn't really a nostalgia reread, as much as a general reread, as I was planning on doing a refresher for reading The Ghost Brigades. (Which I will be starting as soon as I finish writing this review.)
Stock standard in so many ways, ARC Riders left little to no impression on me. In fact, I doubt I could tell you much about the plot tomorrow. It's not that it was bad. It was just supremely "meh."
