I just finished reading Headhunters. I thought it was an interesting story, but I really didn't like how hard the author tried to make the dialogue seem casual. Words like "yer" instead of "you're" and "ta" instead of "to" were really starting to drive me insane, especially since they were Spartans talking.
That being said, the stealth aspect was pretty badass, and the Spartans themselves were interesting enough. My favorite part was probably the Spec-Ops Elites with the red energy swords. Those dudes seemed rather frightening. :D
So what did you all think about it?
