Diana Moore is thirty-three and about (so her Aunt Margaret predicts) to have the best three years she's ever had. Which is a relief since tomorrow she's facing The Biggest Day of her Life so far. A friend's wedding, to which her ex is also invited. And Diana is going-alone. But somehow Aunt Margaret's got it wrong. And next day all thoughts of weddings and exes seem absurdly irrelevant. For Diana is really alone. The car containing her mother, father and only brother has collided with a large truck on a small road. And from that moment on everything she's know is changed. Including Diana.
