For another novel about a woman in a coma, but in a different genre, try [[After You'd Gone by Maggie O'Farrell]] (incidentally, one of the saddest but most brilliant books I've ever read). And [[Black Eyed Susans by Julia Heaberlin]] is an excellent thriller about a teenage girl abducted and attacked.
