Ten years later, my life is in danger, and Aiden is the only one who can offer the protection I need. I don’t have a choice, because the man and the life I chose instead... They're about to cost me everything. I know Aiden hates me, and he has every right to. But maybe this is my chance to tell him the truth. I really did love him. I always have. And maybe it’s wishful thinking, but Aiden and me… We’re more than a memory.
