Range of Motion by Elizabeth Berg. "If you haven’t read any Elizabeth Berg, I’d suggest checking one of her books out of the library to see what you think. This is one of my favorites, about a woman, Laieny, whose husband is in a coma after he was hit on the head by ice falling from a building. Lainey has great faith that he will recover, and tries everything to coax him back to consciousness. It could be treacly, but somehow it's not. Very beach booky, I think, though her writing has a certain elegance."
