Dozens of children respond to this peculiar ad in the newspaper and are then put through a series of mind-bending tests, which readers take along with them. Only four children-two boys and two girls-succeed. Their challenge: to go on a secret mission that only the most intelligent and inventive children could complete. To accomplish it they will have to go undercover at the Learning Institute for the Very Enlightened, where the only rule is that there are no rules. But what they'll find in the hidden underground tunnels of the school is more than your average school supplies. So, if you're gifted, creative, or happen to know Morse Code, they could probably use your help.

    I decided to read this book because a lot of my friends encouraged me to try out the book. Since so many friends made me read it, I decided to check it out thinking it would be a normal book that I read every day. However, when reached the end of the page of the book, I realized that I was wrong and It was the most terrific book I ever read. I think people should try the book because it's a really good book for people who love adventurous and mysterious books.
