First off, Xenocide is a very wishy-washy novel. Card really jumps around A LOT with the characters and their motivations, but, it must be understood that Xenocide is simply a bridge between "Speaker" and "Children of the Mind." Obviously Card had too big a story to condence into one novel and wanted his readers to witness the slow development of his characters first-hand. The Ender books are certainly not everyone's cup of tea, but anyone with a good taste for human-based speculative-fiction won't be disappointed if they take the time to read all four. All great fiction must be read and re-read to be appreciated. There. I've said it.
