Maybe, but the show has strayed pretty far from the books. Remember the book series is called “A Song of Ice and Fire”.
Martin has claimed there are two additional books, one he is in the process of writing and one after. He is also a consultant on the show. Maybe Daenerys has the ability to resist fire. This would counter the Ice King. Remember the only thing that kills white walkers is dragon glass and Valryana steel. Just so happens she is Valeyan and is the mother of dragons.
Do mothers of dragons get maternity leave?
The dead ones, of course, didn't.
