THIS CONTAINS SPOILERS!!!!!!!!!!!!!
From how it ended everyone seemed to be happy,
Chaol and Nyse...
Rowan and Aelin
Aedion and Lysandra
and it seems like something is going to happen between Manon and Dorian... weird.
However with two books on the way and the only storyline going now is that Duke Perrington was behind everything and there is going to be a war and Aelins side obviously wins. So as much as it hurts me to say this... book 4 should have been the last book.
