Memory is shot, forget how she betrayed Ciri to the Lodge, but I know she did, heh. (Flipping around for this kind of thing is a weakness of ebooks)
In game I thought she never told him about Yennefer - though that'd be an odd conversation to an amnesiac. Yen's ok in W3, but they play up the snarkiness a bit too much, she does boss Geralt around in the books but not to the abusive degree she does in quests here. You do get to tell her off a lot in Kaer Morhen as she is pretty much irritating everyone there.
Huh, apparently there's a NG+ playthrough, or at least they left fragments of one in the game
