In The Court of the One-Eyed King: A Novella by Buck Starmer

Alex has come to realise that he doesn't like people very much, but when he meets and falls in love with Julia, new and more immediate questions arise, especially when he finds out she is still seeing her ex.
Searching for truth and meaning in a world with seemingly little genuine regard for either was never going to be easy, but when confronted with one existential crisis after another, including the apparent emergence of a super-natural entity, Alex is eventually forced to take a deep look into his own psyche as well as that of those around him.
