I never used to think that there was such a thing as a stupid genius, but that opinion changed when I met Ernie Flynn. Ernie is smart to the Nth degree about nerdy stuff, but when it comes to women or even life, he's clueless. My name is Mary Claire Hammer, and I'm in love with that nerd. The trouble is, I'm also his best friend and roommate. I will always love Ernie Flynn. It just may not be the happily-ever-after kind of love.
