Marvin Redpost is yet again caught in a dilemma. He's been told that he'll turn into a girl if he kisses his elbow, and after accidentally doing just that he wonders if it is really going to happen to him. His voice starts to change, he longs to have pigtails and he even dots his 'i's with a heart in class! What on earth has happened to Marvin, and will he ever be the same again?

This is a charming story, which will give you lots of laughs. Louis Sachar has the ability to bring together the absurd and the real with the perfect ingredients to entertain all children aged 5 to 7 years.
