The Great Brain is a nice, breezy stroll along the beach. Every now and then we have to look past John D.'s eight-year-old interpretation of events to realize he's being had by his older brother, but overall this bookis a straightforward read. There are no complex motivations or emotions here, and no tricky words to trip readers up.
