"There couldn't be something wrong with everyone else in the world. Common sense said there had to be something wrong with her. If she could just say the right things, do the right things, be a little more interesting... It's never going to happen" 
 Oh my, the beginning was just depressing and the forever alone part of me couldn't help but relate a little :'( and hope I'm just a low level nobody, and someday I'll meet Nobody and all will be fixed 
 And I loved the whole Nobody and Null concept, it's very different and interesting. Now on to the main characters: Nix was trained since he was a kid to kill and not feel but he was so sweet and adorable underneath it, and Claire despite all she suffered still managed to be good and not hate people for what they 'did to her' and they both together was perfection, I mean he built her a bookshelf. Nothing more is needed. 
 And when the pace picks up it's great! I wish I could know more about The Society and their doings, but it's okay... 
 And I loved the ending! Nathalie is so creepy! Is there going to be a sequel? I sure hope so
