My Sister Stole My Throne. Now She's Begging for My Help

In my first life, I, Lyra, was the Dragon Crown Princess. Yet, I fell in love with a common black snake, Dorian.

I willingly gave him my precious dragon scales-a piece of my very essence-so he could fully transform into a dragon.

But the moment he transformed, he plunged a sword into my heart. Then, he turned and knelt before my sister, pledging his allegiance to her.

It was then I realized Dorian had always been my sister Celeste's puppet.

"Sister," Celeste had said, "You have no ambition. You care more for love than power. What future could the Dragonkin have in your hands?"
