the debut novel
Faux Semblant
a psychological thriller
Step into Faux Semblant, a psychological thriller where the ordinary turns into nightmare. Bill, an unassuming teenager, finds escape in adventure games with Vigo — until Sloan, a young girl seeking freedom, shatters his existence. Behind the appearances lies a far darker reality: the line between fiction and truth blurs, and trust crumbles.
In this oppressive huis clos, every character becomes a suspect, every detail a clue. Is Bill the victim, or the manipulator?

From his whole being came a smell of decay. He was dead…
