Schoolteacher Rosy Winter is dying. Her husband Charlie offers all the relief he can. Rosy's sister-in-law, Sally, offers none.

But Rosy feels something growing in her. A hard knot in her chest. Beyond the homeopathic remedies, the dinner party obligations, the snatched whispers on wards and in staff rooms, a force - murderous, feminine, feverish - is stirring within her...

A powerful feminist retelling of Robert Louis Stevenson's Gothic classic, Mrs. Jekyll is a brilliant, evocative, and lyrical story of one woman's refusal to yield her passion for life, even as her body betrays her.
