She's marrying him because the only thing she needs at the end of the day is his Kingdom, so his death is something she is rather eager to collect. He, however, is marrying her because he is already dying, cursed before he was even born.
Althea Evangeline is the only female curse holder in all of the Realms. When on the way to her wedding, she wakes up with Elemental Markings that her father had taught her to hate with such passion from a young age. Althea is forced into running and hiding, searching for a way out of her destiny while hoping to find the immortal male who knows how to strip her of this magick.
That was until her new magick began acting up, alerting her to sounds and sensations that she had never before felt. Althea is led into a cell where she meets her darling fiancé and long-time enemy, Kylen Noxwell; forcing them to work together to buy time before Althea's father, the King of Aeonia, finds out about the Markings. If he was to find out, Kylen knows he will be stripped of a Queen, and Althea will be stripped of her life. The two of them travel across seas and fight back against the darkness, all in search of the answers they need for the questions they still don't know.
