Only Him by Kennedy Fox
I wasn’t supposed to catch feelings for my best friend’s older brother.
It started with a letter and grew into us confessing our secrets.
Then, he left, taking my shattered heart with him.
Twelve years later, he’s back.
We have to keep our distance. If we fall for each other, everything will fall apart.
But then I’m blackmailed into marrying another man, and the guy who broke my heart is the only one who can save me.
Only Him is a second chance, small town romance and is a repackaged boxed set from the Tyler & Gemma duet in the Lawton Ridge duet series. There's no cliffhanger and ends in an HEA.
