My Alpha Mate's Great Betrayal

Amber receives handwritten love letters along with other gifts on her anniversary with Alpha Blake even though he has only ever given her gifts a few times.

She finds out that he has a lover who he pretends he is seeing because of pack business, but she finds proof that he is in fact cheating.

He treats her like a servant and abuses her emotionally. When she has finally had enough and transferred to her friend’s pack abroad, he loses almost everything and he tries to find her to get her back no matter what.
