Review Detail of Nightsking in Avatar The Last Airbender: Not Avatar

Verry good novel so far! First thought he was just a straight up fire bender because the cover art(Didn't look good at ti) so was a fun suprise! Was a bit hard to read for me in the verry first chapter but ones you go through it is a good novel! (First chapter was also good, but was expecting something else which took me a bit to change my mindset)
