Out of the Blue 

Thirty-somethings Faith and Peter seem to have a charmed life: successful careers – he as a publisher, she as a TV weather presenter – two slightly peculiar but kind-hearted teenagers, and an extremely intelligent dog called Graham. But at their fifteenth wedding anniversary party Faith finds the champagne suddenly tastes a little flat. For, out of the blue, her best friend Lily makes a barbed comment about Peter which sets Faiths alarm bells ringing. Why is he looking so trim and well dressed? And why is he so jumpy of late? As Faiths niggling doubts turn to naked suspicion she feels the chill factor kick in, and, as she tries to recapture the sunny days of her past she is forced to admit that, for the time being at least, the outlook is decidely unsettled. The re-issued fourth novel from the internationally best-selling author of A Vintage Affair.
