First read: 07-01-2008.
Notes: Snape's not quite dead after DH and for Harry nobody else is good enough to take care of him. Very dark descent into madness. I didn't quite understand Harry's internal logic for doing what he did, besides something that resembled depression... I didn't understand why Ginny didn't see her husband was going mad when he insisted on spending all his time in a room with a guy in a coma. The Voldemort element is, really, quite tiny.
