Sister Royal: White Tree Publishing Edition

Beryl Rosslyn Aylmer, known from childhood as Bride, is suffering from seizures. Her young brother, Bonny, calls in Dr. Gildredge, but quickly realises he has made a mistake, for he takes an immediate dislike to the man. Dr. Gildredge is determined to become famous throughout Europe, and diagnoses a rare condition in Bride that he will attempt to treat, and write about it in the medical journals -- whether she recovers or not. Dr, Gildredge soon sees that the only way to keep control of Bride's treatment is to persuade her to marry him, and also stop young Bonny from seeing her. As is to be expected, the outcome is far from straightforward. This story by Margaret S Haycraft is a very readable mix of romance and revenge.
