So what if her daughters can barely remember who she is - how hard can it be? However, a thumb through 'The Secrets of Happy Children' doesn't prepare Dot for the drama of children's parties, accident-prone hamsters and a nanny turned novelist. As if that weren't enough, an old flame makes a guest appearance and a serious illness is in danger of staging a comeback. All in all, it's a miracle Dot ever manages to get out of bed, let alone tackle the school run. But amid the fears and flirtations, the gossip and the grubby hands, can Dot find a way to reach the gold at the end of her rainbow?
