For centuries, the firstborn of House Helsington has been cursed to die young, so the family produces an illegitimate child, Isabella, to take on the curse instead. To get away from her terrible home and live her last days in peace, she wants nothing more than to escape. Her chance comes when Grand Duke Noverdic asks her to marry his son, Cleor. Once she arrives in the north, she is showered with endless affection from both her in-laws and her fiancé... to the point that it's almost suspicious.

The fate of a girl in a BL novel is a tragic one. Girls are either vaguely helpful, evil, or add nothing to the plot. So what happens when you turn into the older sister of a BL novel protagonist? The older sister who dies a tragic death at the hands of a madman who’s infatuated with your younger brother? You go with your gut instinct: hide him. Hide your brother from everything, especially men, that could harm him and you. That’s the task that Kyla Vesta is set with in this life, and a task that she’s determined to complete.
