Jason Kim I read the first book, 'Because of Mr. Terupt, and it is Awesome. You will love the 2nd book as well.
Ellie Levi The third book is even better!! Although, there are some mature themes I would definitely recommend this book. It is called Saving Mr. Terupt
Yeslech If you really liked "Because of Mr. Terupt", this second book might ruin the first one for you. The tone of the second book is completely different than the first and, in my opinion, is very perverted.
