The third wheel is a great book overall. It's about a middle schooler named Greg who is struggling to find a partner for a dance. With the dance coming up soon, only Greg and his best friend Rowley are left partnerless. But a last minute drop out changes the circumstances a lot. Greg ends up going to the dance with Rowley and a girl. Things look good before the dance, but a a lot can happen in one night. If you like comical books this would be great book. Filled with humor, this is one of my favorites. If you every come across it, I strongly recommend Diary of a Wimpy Kid: The Third Wheel for all ages.
