Yes, some might think this is only a children's book, but I am a teen and I loved it! This book is the predecessor to The Mysterious Benedict Society series, but you could read it by itself and still understand what is going on. Maybe that is why I loved it so much.
Basically, the story is about the life of the creator of the Mysterious Benedict Society, Nicholas Benedict, but when he was nine (which makes him all the cuter) and his troubles in an orphanage from bullies to friendships.
In between all of this, he also tries to figure out the mystery behind the orphanage he lives in. The downside: he had a chronic sleeping disorder that makes him fall asleep anytime, anyplace. The upside: he's a downright genius.
I think this is a lovely, well written book that will charm people of all ages. Don't give a second thought about reading it!
