A little girl is transported with the help of magic glasses from the tedium of a summer afternoon into an exciting world of mangrove swamps, spluttering volcanoes and sea where birds fly upside down and wild things threaten to pounce. But she is not alone. Old friends from Moomin Valley - Hemulen, Sniff, Snufkin, Thingummy and Bob - have joined her on the journey, and Moomin too, who rides to their rescue in a stripey balloon. This brand new version of a ‘lost classic’ pairs Jansson’s irresistible artwork with a playful rhyming text by one of Britain’s star poets.
