The first book in that series,
The Kings of the Wyld by Nicholas Eames is absolute freaking gold. I loved the hell out of that book. I will be picking up the sequel soon, no doubt.
The book I'm currently reading, Bloody Rose, has a mention of Tree Ent pornography...
If any of you haven't read them yet, check out the Murderbot Diaries by Martha Wells. The first book,
All Systems Red, won the Hugo this year for best novella and it is very well deserved. It is narrated from the point of view of a security robot which has hacked its own governor module and has dubbed itself "Murderbot" since it went on a rampage a few jobs ago and killed its humans. The corporation scrubbed it, of course, and sent it out to work again, but Murderbot feels guilty and really only wants to hide away and watch a lot of pirated media that it has illegally downloaded.
It's funny, heartwarming, and full of really interesting tactical dilemmas. I've read the first 3 (they are short, quick reads) and can't wait for the fourth.
I also would be remiss if I didn't mention my own books. Click on my sig, but I'm a professional author with a fantasy series out from Harper Voyager called The Saga of the Redeemed. I think it's pretty good. The fourth and final book comes out this fall.
