Marv and the Duck of Doom

Marv must stop Granddad's old enemies, Professor Feather and the Duck of Doom from destroying the park. But Professor Feather is no longer a super villain – he is grandad’s best friend, Steve! So, who is the Duck of Doom’s diabolical new controller, and can Marv solve the mystery to defeat the dastardly duo?

Marv's superhero antics remain fresh and fun in this eighth instalment of the series of early readers illustrated throughout with elegant two-tone artwork.
