I really liked this story for two reasons:
-the two love interests are both in their 40s and widowed which is an age and situation I don't really read of in Regency books
-a Lord pretending to be a Valet (Kenneth) just so he can ride horses with freedom not allowed one of his station and a woman (Rebecca) who works in households after her husband dies but they find a comfort in each other even when "society" would look down on them.

The writing in this book just flowed and it's natural and beautiful. I felt bad for Rebecca.. She helped her father (who is an artist and does silhouettes) but is mostly drunk and mean. He never gave her the credit due for her role in his "artistry". I love how Kenneth stands up for her and never cowers from this mean man. 
The baroness who helps them both at the end was a favorite. She shares a little of herself and helps the two see that they are good for one another, no matter what society would think of them!
