All is Not Enough — Meg Hutchinson

With mounting disbelief, Regan Trent realises that the death of her beloved mother has left her totally at her stepfather's mercy. But mercy is a foreign concept to Sherwyn Huntley. To this ruthless man, Regan is simply an obstacle between him and the Trent fortune. Denied a place at her mother's funeral, cruelly separated from her younger brother, promised in marriage to a sadistic pervert, Regan prefers to take her chance in the wide world. But Huntley will stop at nothing to achieve his cruel ambitions . . .
