Isobel is an intelligent, charming, punctual insomniac, and she enjoys the quiet life. So when she meets older man Andrew at a wedding and marries him six weeks later, her friends are a little surprised. Eighteen months on, the marriage encounters its first test.

Isobel works for a whisky producer, along with Flora, a more flamboyant creature who introduces Flora to her university friend, Jack, who has just returned from travelling the world. Jack offers Isobel a glimpse of what life might be like if she was with someone her own age, she's deeply attracted to him and suddenly the doubts come crowding in. Did she and Andrew marry too hastily and does the age gap matter after all?

A wonderful story about the nature of love, with vibrant, heart-warming characters, from a hugely impressive and original writer.
