Unscentable

Piper rejected her Mate at 21, as he could not scent her, did not know who she was. Unable to handle the pains of betrayal anymore, she moves away to live her life as a human. Piper knows she is unscentable to her own kind, no one has ever even noticed her, has been alone in her pack since she was 10 years old. Leaves her home pack for her own self-preservation and survival, to live her life out in the human world. Mate-less. Bradley Drake suffered the pains of rejection but has never scented out his Mate, how can one be severed by one he's never met? Feels more pain when one rejects him as the Alpha and then rejects his Pack too less than an hour later. How can he find one he knows nothing about? Doesn't know who she is, how old she is, what her name is, not even a description, has never smelled her. Never scented her out as his Mate. Only knows she was once a part of his pack. Can he find her, while she is hidden from him? Can he bring her in? Can he find out why he has never scented her? Can they come together?
