No Longer His Promised Luna

The story

Alpha Caleb Thorne thinks a public post can break Sienna: "100 likes and we're over." For ten years, she was the promised girl of his lineage, forgiving every time he chose Tessa and excused the sabotage of her future. Caleb expects another apology through the mate bond. Instead, Sienna becomes the hundredth like, blocks him, packs his guilt gifts, and heads for a neutral academy where his command cannot reach her.
