It seems that John Green is somewhat of an idol among the YA population. He has his own followers who call themselves Nerdfighters. Obviously I needed to know what all the fuss was about.
An Abundance of Katherines follows a guy named Colin as he heads out on a random road trip after his most recent break-up with a Katherine. Since a very early age he has only dated Katherines and even the most insignificant (the shortest relationship lasted three minutes) count. Colin is too smart for his own good and over analyzes things to the point that they become meaningless (in my opinion). But with the help of his best friend and a brief encounter with a town called Gutshot, Tennessee, Colin learns about the important things in life. And those things are not always necessarily called Katherine.
I thought this book was adorable. I don't think it converted me to Nerdfighter, but it was definitely enough to make me want to follow up with Paper Towns and Looking for Alaska. As one who runs from anything involving numbers, I found the math sections tedious. But I don't think they took away from the enjoyment of the overall story.
Would I recommend it? Probably... Though I think I'd wait to read another of his books first and see if I could recommend that one instead.
