This is my third Georgette Heyer, and definitely my least favorite. I think the setting is earlier than the Regency books I usually enjoy, so the Duke was always wearing "dresses" in gold/purple/lilac with ruffles and emeralds/diamonds/sapphires waving around his fan and offering his snuff box to others to snort. This is not the manly hero by any means. He buys our heroine from her abusive brother to act as his page (she is dressed as a boy). What follows is a story of revenge and intrigue. But our heroine has a disturbing level of hero worship for the Duke, who is twice her age (40 to her 20). The Duke refers to her as 'my child' and 'infant' throughout the story, thus making the romance of the story extremely cringey. I am glad to be done with this book and I wouldn't recommend it. Pick up a different Heyer instead.
