Well, if you're going to have insomnia, this is one heck of a book to have handy. It took me a long time to finish this book because I had so many irons in the fire towards the end of last year. I am so glad that I did pick it up now, because it turned out to be a very rewarding read.Just a few of Danielle's Late Night Review Observations:1) James Rollins writes detail-oriented, science heavy action/adventure. It took me a bit to get used to his writing style, but I have to say it really worked for me. Since I am a self-admitted science nerd, I found the scientific aspects quite interesting, and it usually didn't go too far over my head. I loved Coral Novak's character. A tough as nails special forces operative, who is also a serious brainiac. Which leads me to my next point.2) I think Mr. Rollins really loves and respects women. Painter Crowe and Omaha Dunn are strong, pivotal characters in this novel, but the women really carry the show. This novel is underscored and wrapped in the depths and characterization of women, from the shy, introverted, scholarly, tortured Safia, to her more outgoing adoptive sister, Lady Kara, who is equally tortured, to the seriously twisted villain character (a major spoiler) if you haven't read the book, and then there are the mysterious women of the Ubar descent who trace their origins back to the Queen of Sheba. Although I thought that Lady Kara could have been more fleshed out, I think overall Rollins did a great job of rounding out this book with incredible women.3)Painter Crowe and Omaha Dunn surprise you, because they are a lot more emotional than I would expect tough guy action heroes to be. Painter actually gets choked up a few times. It was sexy. And I loved the image of him running around in his boxers. (I'm a bit boy crazy, I freely admit) I like a man who can be free with his emotions. Omaha is in the Indiana Jones vein, but with a soft-hearted depth that Jones doesn't quite show with women; he's never fallen out of love with Safia, even with the bad mistakes he made. That's another plus with this novel that Rollins is unafraid to stray from gender conventions, and dare I say, stereotypes.4)Going back to point 1, (forgive me, it's almost four am, and my brain is muzzy), I like that Rollins does his research to write a story that is about the possible and the plausible. I loved the fact that he built this imaginative science/fantastical adventure on a foundation of real life facts. 5)The action in this book is hot and heavy. When I said it was detailed in the science facts, don't let that scare you away. Mr. Rollins doesn't let his readers down when it comes to things blowing up, characters in serious jeopardy, and yes, violent, gruesome deaths. Nothing gratuitous mind you. If you like all the hardware and high tech action meeting the ancient treasure hunting motif, you'll be a happy camper with this novel.Wrapping my wobbly thoughts together, I thought this would just be a four star novel because of the fact it took a while to get into the book. However, I have talked myself into a higher rating during this review, actually as I read the incredible imagery in this book at its climax. I was mentally reading with my mouth wide open. A guy who can write with this kind of depth and imagination is a man I want to read more of. I have to give this book 4.5 stars at the minimum.Highly recommended!
