The sequel was terrible (joke) ...

During the Go Between, Leo celebrated his 13th birthday.

Apparently there was a very poorly received follow up to the story when he returned the following year.

Leo was going through puberty so he was a bit of a mouthy, sulky idiot, In fact no one asked him to pass any messages or anything.

The Title.... (wait for it)... The Gobby Teen !

After the game, the King and the pawn go into the same box.
