I almost read the entire book in one evening, I just couldn't stop. James Rollins is master when it comes to writing adventure books and this book is so incredibly engrossing that I just couldn't stop reading. Just one more chapters, and suddenly it's two hours later. The only drawback? The romance, I don't know why, I just wasn't fond of it. I'm not against romance in adventure book, but I want it to feel real, and the romance between the main characters, well it was just corny, one step away from a harlequin novel...but beside that the book was really good!
