This is a really tough one. Because the Night King is an invention of the show, the events of this episode will likely play out in a very different fashion in the books. However, there are several significant character deaths which I do suspect give a sense of who remains alive at the end of the books. The context of their deaths may be very different from what George intends, but the episode probably spoils the fact that they will die.
