Vote your least favorite Wimpy Kid book, Round 14.

Old School has been voted as the 13th least favorite book based on a comment with 18 upvotes, now which one is the 14th least favorite book from what's left?

How this works is that you will comment what your least favorite book is, and the comment with the most upvotes will be elminated from here, and this will continue on until we have just one book left.

• I will not be counting number of comments, l'm only counting upvotes.

• Only one answer in each comment.

• Spin-off books will not be included in this voting.
