Marty Monster
Malorie Blackman, Kim Harley
Danny and June are bored, so June dares Danny to go with her to wake Marty Monster. Over shark-infested seas they sail, climbing up the high mountain where the wolves lurk, past the jungles where the wildcats stalk, round the lake where the blubber blob bathes, to the cave of Marty Monster.
