The Tenor Tuner (An Avondale Story‪)‬

Josh Carpenter is gay, and blind since birth. He’s about to graduate from college, and is already an extremely competent piano tuner. He and his best friend Norman Simms encounter a pair of twins while walking on the beach, and their lives are changed forever, and for the better.
They eventually set up housekeeping with the twins, and begin to live a full life, calling themselves the four gay musketeers.
