An uproarious story, told by Kerry (aged 10) over a rather non-festive Christmas Day in which Mummy and Daddy's marriage explodes in front of both lots of grandparents.  So Kerry and his sister Missy (aged 6) are farmed out while Mum and Dad go their separate ways.  Gran, in Massachusetts, has a lovely spacious and peaceful rural setting for the kids to undermine.  Their city Grandmother - Ga-Ga, as she prefers to be called - has an apartment overflowing with Maxl the dachsund and her many beaux.   Meanwhile, Mum is being courted by her lawyer and Dad is pursuing (he thinks) a sophisticated and understanding fashion magazine editor (actually a desperate-for-a-man social climber.)  But everything works out with Kerry and Missy's help.
