'The writing is joyful, more or less. It's painful, but it's also joyful. The marketing of it is much harder.'

Dr Lucy Ryan's book Revolting Women touched a nerve worldwide: many women can relate all too well to the perfect storm of challenges facing midlife women at work, and everyone has an opinion on it.

Which took a bit of getting used to. In this week's conversation, part of my series talking to this year's Business Book Awards winners, Lucy talks frankly about the learning curve when a doctoral research project becomes an award-winning, conversation-sparking business book, and how she learned to love (or at least manage) the work of promoting it.

From being squeezed down to seconds in her first radio interview to talking sex, drugs and rock and roll with Mariella Frostrup, her experience and hard-won lessons are pure gold to anyone setting out to write - and promote - a business book that makes an impact.
