I really loved this book. Now is a great time to read it as I understand the next one is coming out soon. I follow this author on Twitter @grasshopper2407 so will be looking out for the release date.
This book describes the lives of a contained city after The Event which leaves the world contaminated. The Corporation rule this city. People are unable to have children and they are grown in a lab for the lucky ones.
I also loved the Rose Thief by the same author, which was very different from this book and is one of my most favourite books ever. So if you want to rush to Amazon to buy The Gaia Effect, you may want to grab The Rose Thief while you are there!
