Nora Roberts but that's because of my older coworkers... John, ka-duh... I LOVE Hitchhiker's Guide to the Galaxy, wow naming is really hard when the books are across the room and the titles aren't facing you...
That's kind of like asking what's your favorite Beatles song but in fairness I will answer... Just Listen because it's cute and I love them as a couple.

Have you read any Meg Cabot?
