This was meh. It had rough edges, ok story, but honestly not really worth the read.
I loved the alien world in this, that's the coolest part of the story. I like that we, the readers, got to see through the predators presectium, but I felt a lot was messed with. For example, predators are well known as Yautja since 1994. Why the author decided to change that for this 2006 book was very confusing.
Also, I'm confused why they make a human a "predator" through mind control, the whole thing doesn't feel right at all to what predators do. Hunt, challenge, honorable kill or death. They more likely use him as bait, or free him to terrify the others. Mind control just seems against their honor code, cause it not a fight, it's not a challenge, it not a trophy that gives them honor in some way.
Also, I like that the author made the point of predators change genders, that was cool idea, but on the other hand I felt it defeat the purpose of the system. They gain honor through the hunt, for statues and rank. The higher the rank, the more privileges they gain such as breeding. If they could just switch genders that becomes pointless in retrospect. But I still thought the idea was cool, it just gave me mixed feelings.
I want evolution for these creatures but it still has to feel like something that specie would actually do. Slaves sure, mind-control slaves that fight for them? No... well, ok maybe for entertainment in an arena/gladiator fight, but not for the hunt.
Oh one more thing, there is no way that a group of five people are going to survive on an alien planet, reproduce creating a "native" tribe in 313 years. No way, you'd have so many inbreeding, genetic diseases. Species restoration theories, would indicate inbreed in one generation as the two woman are related mother and daughter. So wrong, so many levels.
