From bestselling author Jackie French comes a compelling book about the choices we make and the chances we never dreamed we'd be given.

1931. The height of the Depression, Sydney, New South Wales

They were diamonds: beautiful, sparkling and irresistible.

Nice girls do not accept employment from infamous Tilly Devine, the brothel owner with jewels on her fingers and a pistol in her handbag. All of Sydney knows her as the queen of crime, ruling an empire of bootleg whisky and gambling clubs, and rumour has it she's quick to pull the trigger on anyone who crosses her - including her husband.

Yet, destitute after her mother's death, Constance McKie realises she has three choices: starve, jump over The Gap, or enter a life no respectable girl would dare consider. When Tilly Devine offers her a role as one of her 'diamonds', Connie finds that perhaps she's not the girl she thought she was.

A diamond's role is complex, demanding, usually glamorous and entirely secret, and kept far away from Tilly's world of gang wars, bribery and blackmail. But when murder is suspected in the mansion that becomes her home, Connie soon learns that it's not only diamonds that are tougher than steel.
