Calling The Soldier - The Chance Encounters Series, #54

Noah, a college student, meets a young man, Levi, a stranger in the army stationed in another country, when Noah accidentally calls Levi on his phone all the way from America instead of his friend. The longer Levi and Noah correspond with each other the closer they get until they confess their feelings for each other. But Noah can't possibly fall for Levi. Because he's stationed overseas, he is a complete stranger.
And to make it worse he's a guy and Noah is straight.
