MARKED BY THE ALPHA WHO REJECTED ME

Three years ago, Alpha Kael Draven began to claim Elara Voss as his mate. He stopped halfway and rejected her. He gave no reason.
Now Elara is a nurse who can't be tracked by scent, and she has built a life of locked doors and careful rules. Then a bleeding man is wheeled into her emergency room, begging her not to let "the man in the black coat" take him.
The man in the black coat is Kael.
Someone has been watching Elara for three years. They know her old address and her shift. They have a photograph of the night she was rejected, with a note on the back in Kael's own handwriting, a page he swears he burned.
Kael wants to protect her again. Elara wants the truth, and she wants it on her terms. The mark under her collarbone still burns when he's near, but a mark doesn't make a mate. Only a choice does.
How do you forgive the man who broke your heart to save your life, when the reason he gave you might have been a lie?
