Could anyone please help me!I have been searching for a book that I don't know the name of(well kinda forgot the name) . It's about a woman who woke up from a coma and has amnesia, she's married to some politician but apparently she's just his wife's lookalike and the only way to differentiate them by a birth mark on the real wife's side or something. So please if u know the story tell me
