I also really enjoy Karen Traviss' Gears novels, as well as her Halo ones. I've also got the first three Mass Effect novels, which aren't too bad. 

I read a bit of everything, from science fiction and fantasy to thrillers, adventures, geopolitical Tom Clancy-esque stuff, historical non-fiction, humour fiction, and so on. Generally, if I'm lent a book or recommended one, I'll check it out. Right now, I'm working on two non-fiction books, [I]The Discovery of Middle Earth: Mapping the Lost World of the Celts[/I] by Graham Robb, and [I]The Great Sieges[/I] By Martin Windrow. After that, I have Bulfinch's Mythology, The Complete Works of HP Lovecraft, Homer's Odyssey, [I]The Savage War[/I] by Murray Brewster, [I]The Hunt for Red October[/I] by Tom Clancy, and a few other odds and ends on my bookshelf I haven't gotten around to yet.
