Dystopian- Definition found on Wikipedia
Dystopian- the idea of a society in a repressive and controlled state, often under the guise of being utopian.
In a fragmented future United States ruled by the lavish gentry, seventeen-year-old Madeline Landry dreams of going to the university. Unfortunately, gentry decorum and her domineering father won't allow that. Madeline must marry, like a good Landry woman, and run the family estate. But her world is turned upside down when she discovers the devastating consequences her lifestyle is having on those less fortunate. As Madeline begins to question everything she has ever learned, she finds herself increasingly drawn to handsome, beguiling David Dana. Soon, rumors of war and rebellion start to spread, and Madeline finds herself and David at the center of it all. Ultimately, she must make a choice between duty - her family and the estate she loves dearly - and desire.
Wither by Lauren DeStefano

Her husband, Linden, is hopelessly in love with her, and Rhine can't bring herself to hate him as much as she'd like to.
