I'm guessing this book got its young adult label just because one of the characters is an eleven year old boy. If so, I hope that doesn't stop older readers from reading it. This is an intelligent story that broaches some important medical debates that are far from being settled. Wakely's take on those debates- in the form of two opposing characters, who each state their case in convincing fashion- will keep you reading to the touching, clever ending. There's the possibility of a sequel here, although Wakely had better be careful to not just rehash the plot, since it's hard to see how a second book with the same theme could be better than the original. Also read Flowers for Algernon (if you haven't already) since that book is in the same vein as An Audience for Einstein. Recommended.
