Change of Heart by Barbara Anderson (Jonathan Cape, £16.99).

IT takes an ambitious author to create a first-person narrator whose raison d'etre is to be trying.

Readers demand rewards for spending time with someone like Olly Perkins, the anti-hero of this novel but in here we have to look harder for the pay-off.

At 75, Olly is pedantic, pompous and does not do emotion.

He has a routine marriage to Hester but struggles to contain his frustration with their son, Copper.

After a heart episode, he looks again at his relationships and vows to try harder.

Anderson, who did not start writing until she was in her 60s, has a gift for one-liners.

When Copper remarries Hester asks Olly where their son's ex-wife is. "Probably throwing up in the powder room," he answers.
