After the devastating loss of her parents and the destruction of their pack, Milena Stonehurst's world was left in ashes. As a former Alpha and Luna's daughter, she's struggled to find her place in a world that seems determined to crush her. She was forced to do hard labor and anything that a typical servant should be doing, which is so far from the life that she grew up with when she was still a child. Not to mention, she was also being treated like trash by the daughter of the Stormhowl pack that absorbed their pack before.
Milena's life has been miserable since then. But, she meets Angelov Thelonius Rhinelander, the charismatic Alpha of the Thundercrest Pack, who becomes her beacon of strength and hope. Years later, when their paths cross again, Milena is blindsided by a shocking request from the enigmatic Alpha: he needs her to pretend to be his Luna. As she navigates this new reality, Milena must confront the darkness of her new life. Can she find a way to overcome her doubts and trust the one person who once brought light into her life? "Pretend to be My Luna and I'll give you anything in return."
