Niall doesn't speak to his neighbours. He doesn't speak to anyone. Avoiding conversation is easier than the pity and impatience he senses from everyone the moment he opens his mouth and nothing comes out. Since he split up with his partner years before, he hasn't had much to do with anyone and that has suited him just fine. He has his dog, Zen, for company. Zen doesn't care that Niall can't get through an entire sentence without stuttering. Zen is all Niall needs. And that's how it would have stayed until the day a new neighbour moves in next door.

Zak is Niall's exact opposite—twenty-three years Niall's junior, bubbly, gregarious and never shuts up. His arrival fills Niall's quiet life with constant noise and constant company. Zen appears to have defected, and Zak doesn't seem to even notice that Niall rarely speaks. Gradually, Zak's endless patience brings Niall out of his shell. To Niall's surprise, he suddenly has a friend, a confidante and perhaps something more.

And he didn't even have to say a word.
