The Gentle Queen: HOTD

a young Lillian Hightower's world is shattered when she is forced into a loveless horrid marriage with the king Viserys Targaryen. Stripped of her freedom and subjected to unimaginable cruelty, she embraces a facade of positivity, clinging onto hope. But as the weight of her burdens threatens to crush her spirit, betrayal lurks in the shadows. When she is abandoned by her sister and friend, she vows to protect her children at all costs with blood and fire even against a dragon she once loved
(PS: Viserys is horrible in this it is a AU Viserys so be prepared)

(All rights go to HOTD writers unless it was not in the show then it is my idea and rights go to me )
