The Ugly Truth was indeed a good book. It has family members being together, which is of course great, and Greg is also facing puberty. That is where the problem is.
Greg has to face puberty, and loses his best friend, Rowley, early in the book, It isn't really Greg, but of course, it's really funny.
He tries to get into a commercial, has a Lock-In at the school auditorium, and many more funny things.
The Ugly Truth is a great book for middle school kids who are experiencing puberty.
