Alpha King's Lost Luna

Cassandra Keller was wolfless. She lived in a small pack and ran a small clinic with her friend Marley. When the hunting festival came, she had nothing to expect because she was forbidden to enter the forest for her inability.
That morning, she was called by the Alpha for an emergency. She went there in no time only to find the patient to be the son of their Alpha King.
The Alpha King was not only the king, but also her mate who abandoned her five years ago.
