Book 4 in the Fever series makes the previous books seem like a long noisy hawking of the throat before KMM could begin to heave the gut of the story you've been waiting for. A reminder that each book is a single thread tightly intertwined to form one comprehensive narrative. After the hairy cliffhanger in book 3, you might be foaming at the mouth with...fear?...exuberance?...to dive into this continuation. So, when it opens with Dani as the narrator, you'll be tempted to look for somewhere to go curl up and die (Like, no fecking way, dude! I am the Shit!) Maybe you are, Dani, but you sound like a gangsta-wannabe valley rat instead of the tough-shit Irish tween heroine we want you to be. Thankfully, Dani doesn't narrate for long. For those of you who've been clawing through three books in need of some Mac/Barrons animal sex, be careful what you seek. That wait is over, but it doesn't come served on a bed of roses. It's too clouded and chock-full of foreboding. Barrons at his most charming might be enough to temporarily sate but it does not sustain. There's a lot of unneeded filling in the middle but the ending--another cliffhanger, the most painful one yet--is constructed with great energy and creativity. The mirrors, the otherworld critters, the colorful dimension hopping, awww the beast with crimson eyes...it's a magical ride accompanied by a story that does the imagery justice.And when you finish the last page, you are forced to trust KMM. No way did she do what you think she did. Nooo! Fuck, Nooooooooo!
