There's a baby on my doorstep.

A car seat. A diaper bag. A folder of paperwork with my name on the birth certificate. And one short letter from a woman I barely remember from the one drunken night I've spent the last year trying to forget.

I don't know how to hold a baby. I don't know how to make a bottle. I don't know what half the things in this diaper bag are.

I know one person who can help me.

Maddie's been my best friend since we were kids. My first kiss. My first love. The girl I never quite got over when life pulled her halfway across the country from me. She's the last person I should be asking to drop everything and come home.

She's also the only person I want here.

When Maddie shows up at my door two days later ? exhausted, gorgeous, and ready to teach me how to hold my own daughter ? something in my chest cracks wide open.

I'm going to be a good father.

And if I have anything to say about it, Maddie isn't going back to Tennessee.

Includes: a baby on the doorstep, a single dad who's never held a baby in his life, a heroine who's been secretly in love with her best friend since she was sixteen, a cross-country move, forced proximity in a one-bedroom apartment, mutual pining, late-night feedings, kitchen-sink baths, slow-burn confessions, and the kind of happily ever after that comes with a ring and a future.
