I absolutely LOVE this book! The Mysterious Benedict Society is a series by Trenton Lee Stewart. I would recommend this book for kids ages 9 and up, for some tricky dialogue and a vast vocabulary used.
An ad comes up in the paper, catching many people’s eye. “Are you a gifted child looking for special opportunities?” Dozens of children take part in a series of difficult tests. (It’s also fun to try and figure out the answers yourself, as a reader!) Only four children will succeed. Those special children will have an important job: to go on a secret mission only the wittiest and most resourceful children would be able to complete. Will they succeed? Or will they fail?
Something I really liked about this book was that it was unpredictable. Usually I can guess what’s going to happen next, but when I read this book, I guessed one thing and something I’d never even thought of before happened. The other books in this series are called The Mysterious Benedict Society and the Perilous Journey, The Mysterious Benedict Society and the Prisoner’s Dilemma, The Mysterious Benedict Society: Mr. Benedict’s Book of Perplexing Puzzles, Elusive Engines, and Curious Conundrums, and The Extraordinary Education of Nicholas Benedict. I recommend this series to kids who like tricky puzzles and big words.
