Reynie, Sticky, Kate and Constance are extraordinary children. When an advertisement comes out in the paper asking for children to take a test, our four heroes will make their way to answer the advertisement. They will run into all sorts of problems that they have to surpass. Each one will have to push themselves to the limit to help Mr Benedict try to save the world and everyone in it. I loved this book. There was no language and best of all No PDAs lol. It was an adventure from start to finish but I did find the middle to be dragging a bit. I believe this book would be enjoyed by children and the young at heart. :D Highly recommend!
