Summary: A medicore follow-up
Review: If you haven't read A Signal to Noise as this book expands on several ideas and plots setup there. The same complaints I have about the first book, I have about the sequel: the characters remain superhuman in many aspects and although I think this book does it's predecessor justice, I think that Nylund could have done a much better job finishing out the plot line. I, for one, hate open-ended conclusions and this book does just that. And chances are, there won't ever be another book to follow up on this.

Summary: A great read!!
Review: My wife bought this book for me as a gift, and I read it before reading the first book. It was fantastic! As a writer I know that the first line, or at least the first page, is supposed to "hook" the reader. This one was fantastic and hooked me instantly, espcially since I hadn't read the first book. The book starts with a bang and the pace never lets up until the very end when things get so weird it's hard to imagine the reality he's portraying, but I *like* that! The whole reason I read sci-fi is to be drawn into visions of a reality I would never imagine on my own. It's hard S.F. but with strong characterization. Each character is unique and clearly defined. Bottom line: I couldn't put it down! I heartily recommend it.

Summary: Extremely Imaginative
Review: Nylund takes the reader on a "fantastic" journey. Earth is destroyed and only a few lone survivors are left to forge an existance on the moon. But the twists and turns never stop until the climactic end. The physics Nylund presents his readers in this epic are truly on the cutting edge of scientific thinking. With "alien" technology, humanity can achieve new levels of existance which can cause more problems than good. Nylund shows the surviors strife to retain their humanity and existance in the grand sceme of the unforgiving universe. Plus, the last half of the book was such a "wild ride," I couldn't put it down!

Summary: Clever and fast, a very satisfying read.
Review: This book doesn't waste any time. I found myself completely engrossed in the story at 10 pages. The story is fast, full of interesting characters and universe-sized challenges. Nylund's perspective of human potential and human nature is impressive and creative.The science in this book is also interesting, but rather shallow and opaque; all the interesting technology is "alien" and is not described on anything beyond a superficial level. That's why I gave this book 4 instead of 5 stars.

Summary: Not half as good as Signal To Noise
Review: While the very enjoyable Signal To Noise took an idea and made it plausible through rooting it in a coherent and therefore believable reality, A Signal Shattered reads as something spat out at a great rate - and without much thought. It follows the virtual end of the human race and the struggle of Our Hero to make use of those he saved and his former business parters' machinations and insanity. However, the sense that the characters are actually rooted in humanity is lost through their apparently straightforward intelligence increase and their step-by-step progress through to a disappointingly mundane conclusion. References to the first book are given throughout in choppy paragraph form, written as an afterthought for those reading the book in an aircraft lounge. Read Signal To Noise (or better still, A Game of Universe), but it's best to skip this sequel, no matter how great your love of speculative mathematics.
