The get_queryset is used to return customized queryset not the context. To get context you have to override get_context_data so rename get_queryset with get_context_data like this:

class BookNotLogged(generic.ListView):
    # rest of code

    def get_context_data(self, **kwargs):
          context = super().get_context_data(**kwargs)
          context.update({
            'book1':Book.objects.get(id="2"), 
            'book2':Book.objects.get(id="3"),
            'book3':Book.objects.get(id="4"),
            'book4':Book.objects.get(id="8"),
            'book5':Book.objects.get(id="9"),
            'book6':Book.objects.get(id="10"),
            'book7':Book.objects.get(id="11"),
            'book8':Book.objects.get(id="12"),
            'book9':Book.objects.get(id="13"),
         })

        return context
