This is the plot]

When Seren Thorne returns to Castle Black, the memories of a brutal past come rushing back. Raised under the oppressive hand of her father, the infamous Ser Alliser Thorne, Seren was forced to flee the unforgiving life she had known. Now an adult, she returns not as a broken woman but as a healer and fighter determined to carve her own path. With the threat of the White Walkers looming, Seren's strength and independence quickly earn the respect of the Night's Watch, but not all is peaceful in the shadow of the Wall.

Jon Snow, the newly appointed Lord Commander, finds himself torn between duty and an undeniable connection to the fiery, protective woman who challenges everything he thought he knew about loyalty. Though their love is forbidden by the vows of the Night's Watch, neither can deny the growing bond between them. As tensions rise within the Wall, both from the looming supernatural threat and the betrayals within, Jon must find the courage to protect the woman he loves.

But not all threats come from the dead. Seren's father, Ser Alliser Thorne, will stop at nothing to reclaim control over his daughter-and the power he lost when Jon Snow rose to power. As the White Walkers press closer, Jon and Seren must face the battles that lie not only in the North but within their hearts. Beneath the Frozen Sky is a tale of love, survival, and the unbreakable bond formed beneath the shadow of winter's wrath.
