Those of you who read these posts a lot and those who have read some of the things I wrote, must know by know that I really like genre-crossing.
For those of you who also like it, I recommend Scott Sigler's work.
He has a free podcast of several of his novels. I listened to
the first one, Earthcore and I really enjoyed it.
It starts as a sort of horror story, then turns into a sort of action/crime, and ends up as science fiction story, and it's really good writing. I still haven't got the paperback version, but I think the podcast was a really good introduction to his writing, as he's a very good performer.
