The Reckoning by Kelley Armstrong

Fifteen-year-old Chloe, a necromancer, struggles to understand her feelings for werewolf Derek and his sorcerer brother, Simon, while seeking a way to enter the headquarters of the sinister Edison Group and rescue her aunt Lauren and friend Rachelle.

Woe is me. This ending...ASDFGHJLK. Other than that, the story was pretty good. However, I really didn't like how some things weren't made clear, how some of the “big” characters or organizations didn't even show up, and how abrupt some things were. And, of course, I'm suffering because this is the third book...of a trilogy...it's over...there's no more...asdfghjkl GIVE ME MORE OF DEREK AND CHLOE.
Speaking of Chloe, I like how more...mature she has become. She actual follows through with putting her foot down. Though, I could've done without all those times she TRIPPED.
And then there's the other person who used to piss me off: Tori. Tori...THANK YOU KELLEY ARMSTRONG FOR MAKING TORI MORE LIKABLE. THANK THE LORD. THANK THE PUDDING CAKES. Tori is much more tolerable in this book. She's actually kind of useful this time around, though her temper lowers her effectiveness, though Armstrong usually uses Tori's recklessness to further the plot.
And that's all that I really wanted to get off my chest. Time to scan through the extras and novellas...

A well-written ending to a well-written trilogy! I'm a bit sad to leave Chloe, Tori, Simon, Derek and everyone after three books about their escape and adventures, but I liked how it ended, so I'm ok.
