Milo Kick is no longer Mum's little 'angel'. Five months ago something happened - something only Milo knows - that changed him into a 'monster'. Unable to cope, Mum sends him to stay with Cressida Bell, an old family friend, who lives by the sea. Gradually, Milo becomes obsessed with stories about wild Captain Jellicoe who lives in a nearby cave and who, in turn, has his own story to tell. It is a story that will change Milo's life forever. It is the story of Mighty Fizz Chilla.
