Yesterday’s Letters by Kassandra Lea

Matthew Dalton hasn’t been back home in longer than he cares to admit, but a letter brings him news and soon he’s stepping back in time. Going home, to a place he doesn’t visit nearly often enough.
Daniel Ellis, on the other hand, has never left. He’s always stuck around, waiting for the man who stole his heart to return. When tragedy brings Matthew home, Daniel sees this as his opportunity.

The only problem? Daniel can’t bring himself to voice the feelings he’s kept buried deep inside all these years. So he gives Matthew all the letters he’s written over the years and never mailed. Will a box of love notes be enough to make Matthew stay?
