'Shocking and entertaining. The surprising story of the campaigning women who changed Britain.' Virginia Nicholson

'Full of fascinating historical detail and colourful characters... A great story, beautifully told.' Kate Humble

When Mrs Pankhurst stormed the House of Commons with her crack squad of militant suffragettes in 1908, she wore on her hat a voluptuous purple feather. This is the intriguing story behind that feather.

Twelve years before the suffragette movement began dominating headlines, a very different women's campaign captured the public imagination. Its aim was radical: to stamp out the fashion for feathers in hats. Leading the fight was a character just as heroic as Emmeline Pankhurst, but with opposite beliefs. Her name was Etta Lemon, and she was anti-fashion, anti-feminist - and anti-suffrage.

Mrs Lemon has been forgotten by history, but her mighty society lives on. Few, today, are aware that Britain's biggest conservation charity, the RSPB, was born through the determined efforts of a handful of women, led by the indomitable Mrs Lemon. While the suffragettes were slashing paintings and smashing shop windows, Etta Lemon and her local secretaries were challenging 'murderous millinery' all the way up to Parliament.

This gripping narrative explores two singular heroines - one lionised, the other forgotten - and their rival, overlapping campaigns. Moving from the feather workers' slums to the highest courtly circles, from the first female political rally to the first forcible feeding, Mrs Pankhurst's Purple Feather is a unique journey through a society in transformation.

This is a highly original story of women stepping into the public sphere, agitating for change - and finally finding a voice.
