One of my favorite authors and podiobook performers Scott Sigler is fortunate enough to have one of his works being released in print on Tuesday April 1. Leading up to that he is releasing a free PDF of the book through his publishers website, available here. The novels are very well written and are enjoyable reading. I will warn you, Scott is a sick and demented individual and his novels are much the same way, so if you are easily disturbed or do not enjoy horror this is not the author for you.
The novel is also available in an audiobook format here
