'Entertaining historical fiction with Jane Austen vibes' – Good Housekeeping

Inspired by real history, Rules of the Heart is the sweeping new novel from the bestselling author of The Other Bennet Sister, Janice Hadlow.

When I love at all, it is with my whole soul - my heart must be torn to pieces before it can forget . . .

England, 1794. Lady Harriet Bessborough seemingly has it all: wife to a lord and sister to a duchess, she is welcomed in all the most fashionable circles. Yet she yearns for something her marriage has failed to offer: true love.

When she meets the captivating Lord Granville, twelve years her junior and a famous heartbreaker, she at first dismisses his advances as opportunistic flattery. But then she sees another side to him – a side she realizes she cannot resist.

As she plunges into an all-consuming affair, Harriet finds herself torn between her duty and her deepest desires. For in a world where appearances are everything, each anxious but besotted step she takes leads her ever closer to scandal and ruin . . .
