I love Matt Reilly's books. Fun, fast paced action books are great when you don't really want to turn on your brain but want something more stimulating than tv. I think his biggest asset is his meticulous planning of his books. I met him at a signing and she goes through and basically storyboards his books much as he would for a movie. Sometimes you can kinda tell he's writing it to become a movie, but he is also a screenwriter so I guess that makes sense.
BTW, your father was reading contest and talking about things that weren't possible? The story is full of space-teleporting monsters and a ton of things that don't exist. It seems like physics and many other science thoughts should be suspended the minute a lot of that stuff starts happening.
I would suggest reading Ice Station, Temple, Scarecrow, or 7 Ancient Wonders if you haven't. Ice Station is my favorite.
