About the Author

Nadine Theiss

Mystery, romance, and the supernatural, told in one voice.
Get to know the person behind the stories.
Nadine writes across genres and refuses to stay in one lane. Mystery, romance, and the supernatural all show up in her books, often in the same chapter, always with the ordinary tipping into the extraordinary.

She started telling stories at thirteen, first in the margins of school notebooks. That habit turned into a career, and now into the novels her readers wait for.

Her degrees in Modern Languages and Psychology shape how she writes: characters who think in layers, stories that move easily between cultures and languages.
Two Names, One Storyteller

About the Two Names

Nadine Theiss and N. Theiss are the same person, writing for two different rooms.
One name carries the romance. The other carries what the romance won't say out loud.
Light Side

Nadine Theiss

Fiery romance and grounded paranormal tales. Passion, resilience, and light found in the dark. Endings you can trust.
Dark Side

N. Theiss

Darker, bolder, unapologetically taboo. The stories Nadine doesn't write under her own name, for readers who want to go further.

Life Between Books

When she's not writing, Nadine is usually somewhere new: a different country, a different language, a different set of streets to get lost in. Home is wherever her family and her pets are waiting, the two things that ground her between trips.
