This book is very gripping. You get a real emotional bond with Alex as you see him go through so much: Normal life, the death of Ian Rider, Training, Sayle Enterprises, ecetera, that you actually miss the character after you have turned the final page. The plot is carefully worked out and well put together with very good consistency. There were no boring parts and Anthony Horowitz gave excellent descriptions of each character as they were introduced. These characters were also very memorable and there was no need to remind yourself of their roles as you read.
I give Stormbreaker a five star rating!
