BRILLIANT! 
 This book was absobloodylutely brilliant. 
 It was original and fast paced and thrilling and possibly one of the greatest young-adult books i have read in a long, long time - particularly as it wasn't about vampires. 
 I loved the characters and the plot and the writing, and even though I must be the last person in the world to read it, I can't wait to get my hands on the next two. 
 EDIT 
 I reread this book after I saw the movie, and I can honestly say that no matter how many times I read it, it's still like the first time. Still love it.
