Secretive Cowboy

A handsome stranger was riding a horse I knew.
I had to find out if he stole it.
The cowboy turned out to be the next door neighbor's son who returned to our small town after seven years of absence.
Then he galloped his way straight into my heart.
Before long, sparks were flying between us.
Yet, secrets from his past complicated our friendship.
Making out session on the porch increased the complications even further.
Then a mutually important person left behind letters for us with life instructions.
Those letters changed everything.
It was time to find out the truth.
