When she grew up, Ruth would say that she could place the day that her mother had decided to go away.

She didn't know the actual date, but she recalled the occasion: it was on the afternoon of a wet day, early in 1942, during a visit to the cinema. She thought she could even pinpoint the exact moment at which Iris had made up her mind to go, leaving her only child behind. Neither of them could have guessed then that they would never live together again.

Spanning the second half of the last century, 'My Former Heart', Cressida Connolly's mesmerising first novel, charts the lives of three generations of Iris's family. Ruth will be deserted again, many years later, by a husband she loves, but not before she has had two children by him. She leaves London to live with her uncle, where she creates a new life for herself with another woman. And we follow the lives of her two children, trying to make a place for themselves in the world in the shadow of the family that precedes them.

With its large cast of fascinating characters, this is an outstanding novel about families and their ability to adapt. It surely marks the beginning of a long career as a novelist for Cressida Connolly.
