I read Intelligent Life in a few days, and I really, really enjoyed it. The ending wasn't what I expected, but I loved how everything linked together in the end, and how the randomness developed throughout the book. It's also really funny, and I kept laughing out loud and got some really weird looks... Jonathan was a fantastic main character because even though crazy stuff happened to him, he wasn't super cool, or over intelligent so he never got on my nerves and I found myself relating to him a bit. It was an interesting plot, but it was really nice to read, and there are facts at the beginning of each chapter which were amazing. Some of them were funny, some creepy and some just outright weird. The short chapters made it easy to read, especially if you know you really ought to be doing something else. My nineteen year old sister read a bit and loved it as well. There wasn't a bit in the book I got bored at, or wanted to change. When it wasn't filled with action, it was filled with science and that worked really well for me. I loved it. I think anyone in pretty much every age group will enjoy it, and you don't need to know much at all about science to understand and enjoy it. A very different sci-fi book to any before, but it was definitely an amazing one. I can't wait to read the next one!
