My Fiancé's Twin, My Regret

For five years, Stella protected Lucas with her life. Everyone thought she loved him. Lucas thought so too, and he despised her for it. But when Stella disappeared in a zombie siege, he uncovered the truth: every sacrifice she made was for his dead twin brother, the man she had truly loved. Too late, Lucas realized what he had lost. And in the end, he could only repay her the same way his brother once had—by dying in her place.
