This third installment of the House of Rohan involves a female Rohan, Miranda who is the daughter of Adrian and Charlotte from the previous novel. She is a strong and willful yet still incredibly sheltered. Lucien who is the main anti-hero has the backstory to his suffering and revenge plot.
However, I found the depth of his need for revenge lacking considering when it is ultimately revealed that he is aware of his stepmother's madness as well as a victim of her outburst of cruelty. I'm not sure the depth of his feelings for his half-sister was properly developed in order warrant his revenge plot in the first place.
Putting that aside, you still get swept along waiting to see how the relationship between Miranda and Lucien develop in spite of major hurdles and there is a lot!
