Fiona Mountain grew up in Sheffield and moved to London aged eighteen where she worked in the press office for Radio 1 for ten years, handling the PR for presenters including John Peel, Mark Radlcliffe and Steve Wright and traveling with the Radio 1 Summer Roadshow.

Her first novel, Isabella, tells the haunting love story of Bounty mutineer Fletcher Christian and his cousin, Isabella Curwen. It was short-listed for the Romantic Novel of the Year Award in 2000, the first debut novel to reach the shortlist. It was followed with Pale as the Dead and Bloodline, which combine history with mystery and feature ancestor detective, Natasha Blake. Bloodline is the winner of the prestigious Mary Higgins Clark Award.

Fionas novels have been published in America, Canada, Japan, Thailand, Italy, Germany, Holland and Australia. Though having enjoyed writing the mysteries, Lady of the Butterflies, published in 2009, marks her permanent return to historical fiction.

She lives in a seventeenth century house in the Cotswolds with her husband, Tim, a musician, and their four young children.
