Bound by the expectations of her title, she spent years trying to prove to her father that she was more than just a princess and capable of being more than an ornament in his court but each time she never got the chance. Instead, she was forced into a marriage of convenience with the bravest knight in all the kingdom, Reagan Hawthorne.Dahlia thought she would use this marriage to escape the brutal crutches of her father and glide out of her cage but Reagan’s cold disdain was an unexpected prison of its own.
