We read these books as a read-aloud at our house and were hooked! Follow the adventures of 4 gifted children, each with their own unique gifts, as they set out to solve mysteries that include riddles and brainteasers. And you, the reader, will solve the logic problems right along with them! What a "novel" addition to our critical thinking line.
Currently, we are only carrying this book in paperback - please let us know if you would be interested in the hardback edition.
