Anybody Out There, by Marian Keyes (2006, Ireland)

Anna Walsh is a beautiful 30-ish woman recovering from a bad car crash. When she goes back to New York (from her crazy parental house in Dublin) she can't handle Aidan's missing. Then a day she recalls: he's dead. It takes a long way to start living again, but she's surrounded by (peculiar) people loving her. Deep and engaging.
