Wow. I'm actually speechless, and that's rare for me. This is a thrilling mystery – four people in four different eras notice something odd about their lives. They see spirals, and this is related to death, and they wonder about the connection. What's absolutely incredible is that the story is split into four sections which can be read in any order, and the story will still make sense! I haven't tried it yet, but I'm going to test it out! The 'first' section is caveman times, literally, and then the 'last' section is about sending people to live on Mars. It's amazing to read about, and I found it so interesting.
Hints are dropped throughout about the secret of the spirals, and when you think you have worked it out, there is a huge plot twist and you are back to clueless again. It's brilliant! Absolutely brilliant! And when you finally realise the secret – gosh, it's priceless. I dropped the book–physically dropped the book–and my eyes must have been huge. I was so shocked. The book is actually quite creepy, because it's written so realistically and it creates a vivid image. It's good creepy though–don't worry!
I just love this book. What more can I say? It's so amazingly written, and the concept is so original. I bet you have never read anything like it. So why not give it a go? You might be surprisingly pleased, and it's a decision you won't regret. It's a fascinating read, believe me, and it's really up to you to choose how the story goes.
