In the fog-drowned town of Hollow Creek, the Obsidian Grand Hotel waits-silent, abandoned… and hungry.

Barrett Cole, a disgraced architect haunted by a deadly collapse, arrives seeking escape. Instead, he finds a place that remembers everything.

Room 99 becomes Room 100.

A key changes in his hand.

And the hotel begins to feed on his guilt.

As reality fractures, Barrett is drawn into a living architecture of memory-where corridors breathe, walls listen, and every mistake becomes a room you can never leave.

Alongside Esme Quill, a historian uncovering the building's dark origins, he must confront a terrifying truth:

What if the past isn't something you carry…

but something that is building itself around you?

The Guest of Room 100 is a psychological horror novel blending gothic atmosphere, supernatural suspense, and philosophical depth-perfect for fans of haunted houses, mind-bending horror, and slow-burn dread.

Enter if you dare.

But understand this: the hotel doesn't forget.
