Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

Lenora, an orphaned omega, has always known her place: at the bottom of the pack, toiling away in the kitchen while enduring constant insults. Headstrong and unyielding, she often speaks up for what is right—earning her the ire of her packmates, especially the ruthless Lycan King, Jax, and his confidante, Claire.On her twenty-first birthday, Lenora’s life takes an unexpected turn when she discovers that Jax is her fated mate. But instead of joy, the revelation brings humiliation. Jax, embarrassed by their bond, demands secrecy and rejects her outright. When a cruel setup orchestrated by Claire forces Jax to banish Lenora and her closest friend, Noah, tragedy strikes, leaving Lenora shattered and determined to abandon her werewolf roots.Haunted by his actions, Jax tries to bring Lenora back, but she is no longer the omega he once disregarded. Found and manipulated by Jax's estranged brother, Luke—a vengeful outcast—Lenora must navigate a web of lies, uncovering truths about her mate and the dark secrets that threaten to tear the pack apart.As power struggles ignite and betrayal cuts deep, Lenora must rise above the chaos to protect what remains of her heart and her pack. But when love and revenge collide, will Lenora and Jax find their way back to each other, or will their bond be forever broken?
