What a disappointment . I expected so much better. The first two novels in this trilogy were very entertaining and managed to weave both dramatatic historical events with classic family tensions, particulary with the Cheney sisters. Each character including the tertiary characters were well defined. In this one, the other Cheney sisters never even show up and unfortunately it is a glaring omission. Predictable and boring from beginning to end. Sadly, much like the heroine
Output:
NEG
