One thing (lol only one??? not true) that bug's me about Yennefer in the books it's her decision to send Ciri to sorceress school in Aretusa. When Geralt ask her if she had a doll in Aretusa Yennefer says that she didn't have any toys in her childhood (poor girl) and ask him not to ask why and not to ask about Aretusa. It seems she wasn't quite happy there. And we know shr was trying to kill herself in Aretusa. So why she wanteed to send Ciri there 0_o
Because her powers were immense danger not only to herself but also to everyone else. She needed a proper magic training, more than Triss or Yennefer could provide. If you read the chapter about Ciri's time there it wasn't that bad...
