Y/N is an Omega caught between two Alphas who have spent years denying their feelings for her. Steve Rogers is disciplined and protective, while Bucky Barnes is possessive, unpredictable, and dangerously devoted. When Y/N’s first heat triggers an unexpected bond between all three of them, their carefully controlled lives begin to unravel. Steve wants to protect her, Bucky wants to claim her, and Y/N is terrified of what their bond means. But when someone from Bucky’s past comes after Y/N, the two Alphas realize they’ll have to work together to protect her—or risk losing their Omega forever.
