Can Fin make prom night unforgettable (in a good way), dazzle Claudia and win the crown? When Blake - a US exchange student - suggests a Prom Night for the end of term, everyone is buzzing about it. But to be in the running for Prom King Fin has to be on the committee and help organise a BIG party in only two weeks. He already has extra chores at home to help Mum during her pregnancy and save up for the key ingredients to his success: the tux, the limo and a ticket for Claudia, the Prom Queen of his dreams. Fin's going to use the diary again to help him, but on the night will he remember what's really important? Another laugh-out-loud 'Fincredible' adventure from rising star Ciaran Murtagh, with comic illustrations by Tim Wesson.
