I'm a nerdy virgin—glasses, spreadsheets, collection of test tubes, you get the idea—and proud of it.

I don't mess around with unpredictable things like lust, let alone love.

Or so I think...until a gorgeous, brilliant blast from the past kisses me at my sister's wedding. Suddenly, I'm staying up all night with Dr. Connor Sinclair, making out, making plans, and kicking his adorable butt in chess.

The catch? Connor's leaving town in three days Three days! That isn't nearly enough time to spend with this delicious, sexy, oh-so-perfect-for-me man.

So when he shows up at my place the next morning with two tickets to Vegas and a wild plan to roll the dice on forever, I shock myself by saying...yes.

Yes, to a whirlwind romance.

Yes, to saying "I do" in Sin City.

Yes to breaking all my logical rules.

Will this turn out to be the biggest mistake of my life? Or the best illogical choice this nerd ever made?
