Just purchased Dayton Ward's From History's Shadow(ebook). However, I am reading The Shocks of Adversity by William Leisner first, since I borrowed it from the library and it will have to go back.
I also just finished The Shift Omnibus by Hugh Howey. Good sci-fi author, the ebooks are cheaply priced and DRM-Free. You just can't go wrong there. Recommended.
I also recently read Spin by Robert Charles Wilson. Fantastic book.I think it won the Hugo award too.
