My Best Friend's Sister: A Secret Baby Romance

I panicked, and possibly made the worst choice of my life.
My former bestie told me she's engaged to my ex,
And had the nerve to invite me to the wedding!
Kissing my brother's best friend was the obvious solution, right?

Mark came back to our small hometown take over his dad's medical practice,
Now he's stuck being my fake boyfriend at my ex's wedding.
When he tenderly wraps my sprained ankle, sparks fly.
And I'm catching feelings I have no business catching.

The wedding weekend is fine,
Unless you count the part when the bride humiliated me in front of the whole town,
And I found myself in bed with the one man I shouldn't be in bed with.
I can't face Mark after that debacle,
Until a pregnancy test leaves me no choice.

I'm either going to get everything I've always wanted,
Or end up a single mom with a broken heart.
How did I let it get this far?
