Query: My favorite one!

Hello! This is a great book! It's so cool! It will make you notwant to put the book down! The plot is very interesting! I've read the1st, 2nd, and 4th books already but this one is my favorite! I think I read it 5 times! If you liked the 1st and 2nd one, get this! Get the 4th one too! It's also good.
