I've got a pretty great life, if I do say so myself. I made a fortune when I sold my tech start-up, and I've spent the years since partying, drinking, and inviting a parade of women into my bed.

I should be happy, but I feel an annoying lack of fulfillment, and there's no way I'm going back to the work I did before.

Except now she's pregnant with my baby...and I think this is the solution to all my problems. This is what will bring meaning to my life. I'm going to be a devoted father and husband.

Marissa—whose last name I still don't know—wants me to be involved, though she rejects my marriage proposal. But before the baby arrives, I'm going to prove to her that I can be something other than a playboy.

And the rare times I set my mind to something, I don't fail...
