Guys I just found out(through that spoiler review thingy) that it's mostly
a happy ending! Mostly, that is the key word arrhh I'm like really trying to decipher if
that means a character death or Kuviras death or something else. My inner fanboy has
activated from all this hype haha
It was confirmed by the creators months ago that book 4 would have a good ending.
I wouldn't put much stock in the reviewer. They could be telling the truth or could be making the whole thing up.
