The Storm Dragon: Book One
The story of Rhaelle Baratheon and Jon Snow.
While Targaryen blood has always flowed strongly through Baratheon veins, Rhaelle bears its mark. They say she is a curse upon house Baratheon, for as her brother Robert caved in the chest of Prince Rhaegar on the Trident, a lock of white hair sprouted from his baby sister's head.
Now Robert travels to the North, to strike a bargain with his oldest friend and offer both his son and sister in marriage. But Rhaelle does not wish to marry Robb Stark. She has fallen in love with his bastard brother. Circumstances tear them apart, but she will do whatever it takes to be with him again.
