"Sequel to The Devil's Trill Sonata"
Although their relationship has been repaired since the disaster that was Cambridge, Darren has not. His depression has worsened over the years until it is no longer an option to watch the illness play out its patterns. Treatment is a must.
Treatment is also a difficult disaster. When the second attempt at medication goes as badly wrong as the first, and Darren is forced through a rapid deterioration of mood swings, insomnia, nausea and increasingly dangerous thought patterns, his partner Jayden begins to fear that the only end to this disease will also be the end of Darren himself.
Apart from a single glimmer of hope: when Darren's best friend asks Darren to play at his wedding, Darren begins to slowly return to the half-forgotten piano. As he slowly sinks back into the music that he deserted seven years earlier, the shadows -- finally -- begin to fade.
