So far the final book of the Ender Quartet is decent. It isn't mind-blowing, but it certainly isn't bad. Xenocide, the preceding book, started out slow as well.
There has only been one pair of characters I don't like introduced. Their dialogue is simply annoying. I'm not sure yet if that was done intentionally. Otherwise, the characters are great as usual.
The plot is very complex for the halfway point of a novel, yet it isn't confusing. I like it. There are multiple threads and several POVs (kind of, as I consider it to be omniscient). After years of reading YA, it's nice to read those sorts of novels.
The settings are cool as usual. They aren't as flamboyant as those found in space opera, (I consider this to be under the "soft" subgenre) although they suit the book. It's all good.
Keeping things brief, this gets an 86% so far. Hopefully it will improve by the end.
