I've just started reading Mary Jo Putney's Fallen Angel. It is a Regency novel and very reminiscent of books by Georgette Heyer. It reminds me particularly of books such as Bath Tangle, The Talisman Ring and Black Sheep. The dialogue is sparkling and the sparring between the hero and heroine is well done and witty. Clare - a school mistress in a small Welsh village - hears the rakish Lord Aberdare - half gypsy as all the best heroes are - has returned to his estates after a 4 year absence. Clare approaches him requesting financial help for the villagers and the means to make the local mine safer for its workers. Lord Aberdare strikes a bargain with her. She must live with him - ostensibly as his mistress - for three months. After that he will provide what is needed. The book was originally published in the USA and is the first in a series.
