Rejecting to be His Luna Queen

As the first female battle commander of the military from the Waevalon Kingdom, Rachelle Simon believes that she does not need a mate in her life until she knows who she really was or where she actually came from before she arrived at the Dark Soul pack.
She is living in peace until an annoying mysterious brute named Claude Hackworth arrived at their pack to visit his sister who happened to be her Luna and claimed that Rachelle is Claude's mate.
However, she determines that she is not going to utter the words that she is accepting him.
What will happen if Rachelle gets to meet and see her mate again in an unexpected moment but he will not introduce himself as her mate but the newly crowned Alpha King of Waevalon Kingdom?
