I've become a fan of alternating view points. It used to drive me crazy, but now I kind of like it, and it really works here. In fact I know that it wouldn't have been good only told through one perspective. 
 I'm a sucker for these kind of books. The ones that take place over 24 hours or have some kind of time frame involved. Love them! 
 I liked Norah slightly more than I liked Nick, but I liked Nick's chapters better. Norah was more fun, Nick spent a lot of time hung up on Tris. Even though Norah was still dealing with Tal she didn't come off as whiny about it. Nick's chapters were more funny and I really got into some of his rambling thoughts. 
 All the other characters were great, even Tris. They had their place in their story and they fit well with Nick and Norah. Tony/i/e was my favorite. 
 The stuff they do is crazy and so much fun! I wish that I would have had a night as fun as this. 
 Norah's dad makes a small appearance in the book but I think that was one of my favorite scenes in the book and it's such a fatherly thing to do. Even though it ticks Norah off, it's for the best. 
 As much as I loved this story I can't give it 4 or 5 stars. The "F" word is seriously overused in this book and I just could not get past it. I know that teenagers cuss (I know I cussed as a teenager) but it was overkill in this book. I wish that I had this as an ebook so I could count how many times they used it. Seriously, it's everywhere!
