Dan and Sally Oliver and their friend Chloe Hennessey are lucky to be alive. Three years on, after surviving one of the world's biggest natural disasters - the Boxing Day tsunami - their lives have changed dramatically. Dan and Sally are now parents. Dan is enjoying being a stay-at-home father taking care of their young son, and Sally is the bread winner and loves her job as a partner in a Manchester law firm. The arrangement has so far worked well, but when Dan starts to question whether Sally has got her priorities right, the cracks in their marriage begin to appear. Dan and Sally have everything Chloe wishes for in life - a happy marriage and a beautiful child. Dumped by her long term boyfriend just weeks after the tsunami, she's been on a mission ever since to find the perfect father for the child she craves. When she meets Seth Hawthorne, she thinks she may have hit the jackpot. But is Seth the man she thinks he is? A life can change in a heartbeat but IT'S THE LITTLE THINGS is not simply about the moments when everything changes, but also a moving, compelling and inspiring story of how we lead our lives in the days and years that follow.
