Were I to rate this book simply on the plot, it would score far higher. It is beyond intriguing and unfolds at a fairly decent pace. That said, I have major issues with this book, which is why I'm giving it (just barely) two stars. First, this isn't so much a trilogy as a single book broken into three different parts. Compare it, for example, to the original V.C. Andrews Flowers In The Attic trilogy, where each book stood on its own as a complete story. This book arbitrarily ends on a cliffhanger, and in order to get a complete story, you have to purchase the other two books. Which means you are paying over $20 for the complete story. Beyond that is the quality of the writer. While the author clearly knows his stuff when it comes to science, he is in desperate need of a writer. Sentence structure is not his friend, and there are typos galore. As a self-published author who works hard, in conjunction with an editor, to make my books the best they can possibly be, I have become increasingly, wildly frustrated with books such as this which simply do not live up to the implied contract between an author and a reader; a contract which promises not only to tell a good story, but to do so in conjunction with an editor who will make sure that the reader is getting their money's worth as opposed to something which feels haphazardly slapped together. While the story raised questions that I'd love to have answered, I have absolutely no intention of throwing good money after bad in order to find out how the tale ends.
