I made an interesting discovery upon opening the Wit'ch Fire freebie on my Sony reader and finding it was 1800 pages long. It is actually the first 2 books in the 5 book series Wit'ch Fire and Wit'ch Storm. It doesn't indicate this on the Sony website.
Also according to fantasticfiction.co.uk James Clemens is the pseudonym of one of my favorite authors James Rollins.
