Captain Underpants and the Invasion of the Incredibly Naughty Cafeteria Ladies from Outer Space and the Subsequent Assault of the Equally Evil Lunchroom Zombie Nerds (Captain Underpants #3)
Author: Dav Pilkey
Goodreads Rating: 4.16
Full of silly humour. Seems to appeal equally to boys and girls. The blocks of text are short, and every page has b/w illustrations to make the children laugh. Some of it is in comic format. An excellent book to encourage reluctant readers.
