I have read every pred and AVP novel at least 3x each
Here is how I rank them from best to worst.
1. South China Sea (many substories. Well written)
2. Turnabout (slightly less good than the above. Takes place in Alaska)
3. AVP (novel from the movie is a million times better than the film)
4. Big Game (Navajo soldier in the U.S. Army. Serious tribal folklore mixed in)
5. Concrete Jungle (Unique take with a couple of New York City cops. Dutch's brother stars)
6. AVP Prey (Initial take on a female human teaming up with a Pred to fight bugs. Intro of Machiko Naguchi)
7. Cold War (Dutch's brother is back. Kind of trite at the end but good read. Takes place in Siberia)
8. AVP War (Story line kind of weak, but still a pred story
)
9. Flesh and Blood (not terrible, but nothing stands out. )
10. AVP Hunters Planet (just too damn candy ass)
11. Forever Midnight (Just bad, IMO )
