I absolutely loved You Have Seven Messages by Stewart Lewis. I recently found out that Lewis came out with a new novel last month, The Secret Ingredient. I'm going to go and get a copy pretty soon, and add it to the end of my very long list of reads to enjoy! If you follow the link, you can find the first two chapters on Scribd. They're definitely worth checking out, even if you haven't read the other book. The two aren't related at all, however it still is a good idea to check out the first one!!
