My Fiancé Left Me to Die. His Rival Saved Me.

Kidnapped by ruthless gangsters, Luna Voss is betrayed by the man meant to protect her—her arrogant mafia fiancé, Kael Thorne, who assumes her abduction is only a scheme to force marriage. He even orders her captors to keep her as punishment. But the one who steps in is Silas Locke, the new don feared by all, and from that rescue comes a dangerous, irresistible love. When Kael finally understands the truth and comes back begging for the childhood promise they once made, Luna leaves the past behind and chooses the fierce loyalty of the man who found her when she had nothing.
