  • Tears flow

    I was taken aback by my reaction to the first ending of this story, then shocked at the true ending. Rollins always surprises and entertains. Pretty much exhausting at times but always worth the read. On to the next!!!
  • Interesting, but...

    I loved the Indiana Jones meets Professor Langdon characters in this book. I thought it kept my interest threw out it. I only gave it four starts though because, I felt it had a somewhat disappointing ending.... He left it open (yes, I know it's a series of books). Thought it would of had a better ending then it did I would recommend this book to anyone....
  • Rambling drone of a story

    By Txhntr
    James Rollins has a habit of boring us to death with too much setup and too much technical detail. I have read all the Sigma series up to this episode. While some of the stories have been stronger than others, this one by far was the worst. This story is comprised of so much filler by way of technical jargon, side stories that go nowhere, and far too little action that you actually have to try to remember what the story line is as you proceed through the novel. I would recommend skipping this one.
  • The Last Oracle

    This book, and three other Rollins downloads, was missing whole chapters of text. Impossible to read.

    Very interesting. Concept is compelling. Action is fantastic.
  • The last oracle

    By Vinhimself
    If you've read more than one books from this author, you already know the pace of the story. It is very hard to drop the book as the suspense will keep turning pages after pages. I personally really enjoy this one.
