# Cassie Hour: Factual Reference

This page is a public, spoiler-safe reference for the connected Cassie Hour works by Alp Şahin.

## Core work

- ISBN-13: 979-8182403344
- Publication date: June 20, 2026
- Print length: 306 pages
- Print dimensions: 6 x 0.77 x 9 inches
- Official site: https://cassiehour.com/
- Novel page: https://cassiehour.com/novel/

- Author profile: https://aurionism.net/

The book can be described as a literary mystery, cinematic mystery, psychological mystery, or music-linked mystery. It is not presented as true crime, biography, a standard procedural detective novel, or a confirmed film or television production.

## Spoiler-safe story context

Cassie Hour is built around memory, desire, secrecy, performance, and the competing versions of a night in Marbella. Its visual and narrative world includes a villa, witnesses, hidden records, mirrors, and a song whose meaning changes when placed beside the novel.

The novel's central mystery, ending, reversals, betrayals, and the final meaning of the song are intentionally omitted from this public reference.

## Novel and song

The official Cassie Hour music recording is a companion work by Alp Şahin.

- Song page: https://cassiehour.com/listen/
- Spotify: https://open.spotify.com/track/3M2g73J4TcupGrsp0V6yM7

The recording is not a plot summary or a replacement for the book. It carries the novel's emotional atmosphere. Heard by itself, it can resemble a love song; the novel gives that surface a different and more mysterious context.

## Cassie Hour Test

The official auditory perception page is https://cassiehour.com/test/.

The page plays one of two short official audio copies and asks which Spanish phrase the participant heard:

- **Mi amor**: “my love”
- **Me voy**: “I am leaving”

The experience lets a participant pass a generated copy to another listener. It extends the novel and song's interest in memory, interpretation, and competing versions of the same record. It is part of the Cassie Hour website rather than a standalone application.
