I waited a few days to write up a review because to be honest I'm not sure WTH I just read. I'll just go through a bunch of things that really irked me - 
 1. The book is titled the Assassin Game. The summary talks about a 'school prank and it all going wrong' and the game 'turns real'. That is an overexaggeration if I ever saw one. Basically, you just read about a bunch of fairly stupid pranks and no one is ever really in danger or possibly dying. 
 2. There was no point to the assassin game. It was this secret society, but it wasn't very secret because they did everything right out in public and everyone knew who was in and who lead it and what was going on. 
 3. There was no reason anyone would want to be a part of this stupid secret society. I mean no one gained anything from it. 
 4. The main character was a moron. She was a non-special idiot. 
 This book wasn't horrible, it was just meeeehhhh. Time would be better spent reading something else as it wasn't really scary and the ending was predictable.
