Pissed off. First 1 and 2 end on cliffhangers, the second a huge one. Then 3 ignores all that and goes back in time. But apparently the author can't read, since it undoes the already questionable world building of the previous books.
The concept has potential. The author has potential--the first created riveting characters.
But the whole series needs a quality editor to clean up the mess, hone the story telling, and make the world building CONSISTENT. And, of course, to get rid of cliffhangers, which are a sign of a weak author, unable to provide complete stories or unwilling to trust the reader will return if the book is good enough. At least I got it free so only wasted time. Can only imagine fury of reader who squandered limited book budget on these!
