Pretty good. I had high hopes, as I really enjoyed the first book in the series--this one did not come up to that level for me, but I did like it.
Cassandra, the heroine, has a life changing experience at the beginning of the book. She finds out that the people she believes to be her parents were actually her adoptive parents, and that instead of being the child of a wealthy merchant, she is actually the granddaughter of an earl, and is his sole heir. Of course, the laws being what they are, she cannot inherit his entailed property or his title, so the earl has decreed that she marry his male heir, Cassandra's cousin.
Of course, this does not suit Cassandra; she is attracted to a marquess, Simon Fitzgerald.
The action in the middle of the book was slow; Cassandra's rebellion against her grandfather took a long time to develop and she was slow to realize she really loved Simon.
The ending was fun. I liked how Simon's sister stepped in and interfered enough to secure her brother's happiness.
