I will admit that the only reason I initially read this book was because the title includes the correct spelling of my name. Katherine. "And not Katies or Kats or Kitties or Cathys or Rynns or Trinas or Kays or Kates or, God forbid, Catherines. K-A-T-H-E-R-I-N-E." Definitely my favorite quote in the entire book. 
 In the end, I ended up identifying with some of Colin's Katherines in that I break up with more than I am broken up with, hopefully for better reasons than all of his Katherines gave. And despite all the math (though there really wasn't THAT much but just enough to give me a headache because we all know that I'm a math genius) I really enjoyed this book. It was funny. I LOLZed a lot. The footnotes were hilarious but also informative. I could picture the characters (and we all know that makes or breaks a book for me). And, most importantly, my name was mentioned. a lot. 
 Obviously, that's not the reason why I loved this book so much. But, you have to admit, we're all drawn to books, movies, music, etc. that feature our names. 
 Anywho, this was a quick, funny, and adorable read. You should read it. You can also learn some stuff.
