Written in 1921 and winner of the Prix Femina-Vie Heureuse Anglais, an award set up by two French magazines in 1912. The details, including a list of other winners, are in the book Famous Literary Prizes and their Winners, which you can download here.

The dangerous ages are represented by five women from four generations of a well-off, middle-class, privileged family. There is no one dangerous age: Macaulay's characters experience dangers and uncertainites at many stages of their lives. The post-war years have their own dangers, with the aftermath of WWI, a new independence for women and an demanding working class.

I enjoyed Dangerous Ages, but didn't care too much for the characters. If you're interested in Macaulay, The Towers of Trebizond is a much better book. ( )
