I found the first half of the book pretty boring. Stereotypical teenage girl moving to a new school and meeting some moody yet perfect guy. The whole thing just screamed twilight, and Sky's pop culture references got on my nerves after a while. Especially when she spends ages referencing star wars, only to get Yoda and Obi Wan mixed up later on. 
 At around half way through the book it gets more interesting with the whole savant storyline really coming into play and some actual exciting stuff happening. I was close to giving up on the book when the plot got better and I had to finish it just to find out what happens - and I must admit I was intrigued by Sky's past. 
 The book was average. It was enough to make me keep reading, but it was nothing special or memorable.
