"Need" is a tough book to review - while reading it I was totally engrossed and fascinated. It has a slightly creepy vibe that makes you want to close the curtains and stay out of dark rooms. I liked the main character's habit of quoting phobias, it was clever. I finished the book very curious to read the next one. But then as I mulled over the story in my mind, I found myself very disappointed. 
 The book is written in first person as always seems to be the case lately. However, instead of the usual first-person past-tense, it is present tense... This is odd and very jarring at times "I walk here. I do this. I trip. My aunt laughs." The descriptions are barely there which really works during the creepy, in-the-dark scenes but most of the time leaves you guessing. There was a scene where the main character is startled by a car and jumps into a ditch - then she's apparently all scraped up and bleeding - a much more extreme tumble than I'd imagined. There's also more than one instant where the author got mixed up and confused who was where or had a character in two physical forms at the same time. Seriously - an eagle lands on the outstretched, gloved arm of ... a werewolf in wolf form? Oops! 
 The main character is a little too obsessed with her causes - I got very tired of the preaching. And I had originally picked up this book because some reviews described her as "Bella with guts" - um, no - try Bella without brains. She was always either freaking out or running headlong into danger without thought. 
 That being said, those are minor issues. My biggest problem with "Need" ended up being the "need" behind the name. Seriously? That's the 'need'?! The correlation between the "need" and the proposed solution just didn't make sense. Neither did the temporary solution/bandaid that the enemy was forced to resort to. And I never understood why the main character (and certain others) were supposed to be important in the first place. The bits of the sequels that I have read only confirm that the niggly doubts from the first book are fanned and flamed in the sequels. I'd recommend Wondrous Strange by Lesley Livingston instead...
