Penny Baker is coping. Just about. Three kids, one dog, one lovely but sometimes oblivious husband. Tick, tick tick. She is even managing to hold her own among the competitive school mums - if you don't look too closely. But when she finds herself also caring for her elderly mother, diagnosed with dementia, the household is thrown into disarray and Penny finds herself stretched to breaking point trying to meet everyone's needs. Can she make the new family situation work? And is there any chance of finding some space in it all for herself?
