Best in the series so far.  Rather clearcut with some big huge game changers for the characters (versus some murky running around trying to figure out things that did drag a bit in previous books).

Series had been decent so far but not really hooked.  This one hooked me.

Ratings scale used in absence of a booklikes suggested rating scale:

★★★★★ = All Time Favorite 
★★★★½ = Extraordinary Book. Really Loved It.
★★★★☆ = Loved It.
★★★½☆ = Really Liked.
★★★☆☆ = Liked.
★★½☆☆ = Liked parts; parts only okay. Would read more by author.
★★☆☆☆ = Average.   Okay. 
★½☆☆☆ = Disliked or meh? but kept reading in hopes would improve.
★☆☆☆☆ = Loathed It. Possibly DNF and a torturous read.
½☆☆☆☆ = So vile was a DNF or should have been. Cannot imagine anyone liking.  (Might also be just an "uploaded" word spew or collection that should not be dignified by calling itself a "published book." If author is going batshit crazy in the blogosphere over reviews -- I now know why they are getting bad reviews.  Or maybe author should take remedial classes for language written in until basic concepts like using sentences sink in. Is author even old enough to sign a publishing contract or do they need a legal guardian to sign for them?)
