Cathy Gordon has made a discovery. Adopted at birth, she finds out at the age of twenty-eight that she has a grandfather. But when she arrives at a cricket match to meet Frank, there is no trace of him - only an alarmingly sexy man called Nick.

Heading off to Frank's home in leafy Oxford, she encounters a grumpy old man who only takes pleasure in two things. Cricket, and arguing - especially with his lifelong friend, Barbara.

Determined to bond with her only living relative, Cathy takes up the challenge - a challenge which means her path crossing with Nick's once again. But as the summer heatwave continues, Cathy realises that there is more at stake than family ties. Will any of them - including Frank's beloved England team - rise to the occasion?
