Guinevere rides to Camelot to marry Arthur. Except that the real Guinevere died and has been replaced. She tells no-one her real name, not even us. She seems to be Merlin's daughter, sent by him to protect Arthur against some unknown imminent threat, but she has gaps in her memories so there is a sense of mystery as we discover our narrator while she is discovering Camelot.
Re-reading. This book tugs on my heartstrings.
