Jenny Haddon was born in London, England, where she always returns after the travels that she loves. When she was small, her mother couldn't bear reading aloud, so her mother taught her to read at an appallingly precocious age. She wrote her first book with her own illustrations at the age of four but was in her 20s before she produced her first romance as Sophie Weston.

She studied English Language and Literature at university. Choosing a career was a major problem. It was not so much that she didn't know what she wanted to do, as that she wanted to do everything. So she filed and photocopied and experimented. She worked as consultant at the Bank of England and all the time she drew on her experiences to create her Mills & Boon books. She edited press releases for a Latin American embassy in London (The Latin Afffair); lectured in the Arabian Gulf (The Sheikh's Bride); waitressed in Paris (Midnight Wedding); and made herself hated by getting under people's feet asking stupid questions under the grand title of consultant all over the world (The Millionaire's Daughter). She also is an active member of the UK's Romantic Novelists' Association's Committee, and since 2005 is the Chairman.

Jenny has one house, three cats, and about a million books. She writes compulsively, Scottish dances poorly, grows more plants than she has room for, and makes a mean meringue.
