Quiet Types by L.H. Cosway

Maggie Lydon rides the bus to her cleaning job every day. It’s an ordinary existence until she notices him sitting just two rows behind her. She doesn’t know his name, nor anything about him. All she knows is that he watches her and it’s the most exciting part of her week.
Shay Riordan notices her the very first time he takes the bus. She’s captivating, a beauty who moves through the world like no one else can see her, but she’s far from invisible to him. He wants to sit next to her, introduce himself, but it’s hard to do when you can’t speak.
Then, late one Friday evening they both board the bus, and an unexpected occurrence plunges Maggie into Shay’s world, and Shay into Maggie’s.
