After being told that only &quot;rebel fathers&quot; can be admitted to Moominpappa's new club--the Knights of the Catapult--Moominmamma defiantly decides to join a club of her own. Unfortunately for her, she accidentally joins a club of gangsters who revel in dubious and illegal activities. And things only get worse for poor Moominmamma as her wish to be admitted as a club member turns into a difficult juggling act of loyalty between conflicting organizations. Comic misunderstandings, tested allegiances, and frivolous scandals make <i>Club Life in Moominvalley<b> </b></i>an exciting adventure with the whole Moominvalley gang in another classic Tove Jansson tale.
