DNF'd at 65%. Interesting idea but BORING execution. There is nothing "thrilling" about this book. It plodded along. Heck, we didn't even get to plot until about 10% into the book...up until then it was all backstory. i finally quit because nothing of significance was happening, and I didn't care about the characters.
And the almost the entire story is written as narrative. Dialogue, dialogue, wherefore art thou dialogue? Answer: not in this book. It was strange and puzzling and...boring.
It would have gotten only one star, but I though the scientific concept was interesting.
