Mary Jo Putney's "The Diabolical Baron"

The Diabolical Baron (Onyx Historical Romance) - Mary Jo Putney

A really nice "traditional Regency" romance, i.e. kisses only, no explicit sex scenes. Mary Jo Putney's first published book and quite delightful - it stands up well in comparison with her later books, and even features a lost heir, which seems to be one of her favourite plot devices ;-) One of her best characters, Reginald Davenport, appears in this book as a real jerk (this is before he is reformed and becomes a hero in "The Rake").
