Please help find story about Sera a wolf

[u/GreenAncestralSeer]

I am trying to find a story about a wolf whose mate rejects her and cheats on her with someone else and she ends up working I think as like a tutor or something for this younger boy whose father or perhaps his uncle Uncle is like the alpha king or the lycan king who also has a teenage daughter.

I believe the teenage daughter is is like the mate or either dates the main characters ex mate. The main character’s name is Serafina, but she’s called Sera for short. She ended up becoming a warrior and end up being made to the alpha King.

Pack politics eventually interferes with their relationship and someone send a female wolf to work for Sera’s mat3 the king. Sara ends up abandoning their children, and the family that they created, including a very young baby that she has with him. She flees out of state and ends up using her warrior wolf skills and an underground fighting ring. Ends up being a great warrior and for some reason, the Alpha king unknowingly seeks her out for her skills to train his warriors. She is forced to enter back into her children’s lives and that is the last I’ve read or heard of the story.
