The Cruel Prince is in the point of view of Jude, who is an average human taken to the secret world of Faerie by her mother’s first husband, who killed her and their father then took away Jude, her twin, and their big sister to the Faerie world which is a world full of immortals. Still, it isn’t easy on them because they look down on mortals.
Jude, who is really good at fighting, gets hired by one of the princes to join his court of shadows and help him become king. Still, when the coronation was going on, he gets killed along with the rest of the royal family except the youngest prince, who is actually the judge’s enemy, and she kidnaps him.
However, Cardon isn’t evil, unlike the prince that killed his own family, so Jude makes him the king until her brother, who actually turned out to be a member of the royal family, grows up.
The book has quite a bit of action and revenge, but the book is about romance and can be quite entertaining when bored.
