Neighbor’s Secret Baby by Anne Martin

My possessive neighbor just punched a guy in the face for me.
It wasn’t quite the welcome home I would’ve expected.
Five years ago, I gave the enemy next door my v-card.
In turn, he gave me a one-night stand and a positive pregnancy test.
I would’ve taken this secret to the grave.
But his sister wouldn’t be my best friend if she wasn’t able to put two and two together.
And now, I might be falling for the one man I should be staying the furthest away from.
Who’s to say he won’t be the one to run when he finds out the witty kid next door—is his son.
