Showing All the Hopeful Lovers by William Nicholson

Belinda wistfully reflects how much better at sex she is now in middle age than when she was younger. A lover would be nice but she'd never be unfaithful to her husband Tom. So when she discovers he's having an affair, she's more than angry.

The seven days following her discovery see her through a rollercoaster of highs and mostly lows. But when she looks around her, she sees that she's not the only one who's having a bumpy ride. Chloe, her flirty student daughter, tries to set up Jack with shy Alice, yet fails to see that Jack is secretly longing for her.

This is our own familiar world rendered pacy, funny, emotionally on the button and hugely entertaining.
