Undercover Claus

By Justin S Simpson

Undercover Claus
Book One of the NOEL UNDERCOVER SERIES

Nina Hart wasn't looking for danger-only answers. Her sister Lena vanished without a trace, leaving behind one final, chilling message. Now, disguised as a cheerful Santa's helper at a bustling Christmas market, Nina steps into a world wrapped in twinkling lights... and dark secrets.

What she expected: holiday music, smiling tourists, harmless seasonal chaos.
What she found: coded notes, suspicious vendors, a stranger who knows too much, and a hidden network operating beneath the festive cheer.

When a package meant for someone else lands in her hands, Nina is thrust deeper into a dangerous game-one where every ornament hides a clue, every shadow holds a threat, and every heartbeat might be her last. The deeper she digs, the clearer it becomes: Lena's disappearance wasn't random... and Nina has just stepped onto the same deadly trail.

With time running out and danger closing in, Nina must decide who she can trust-and how far she's willing to go to uncover the truth.

A thrilling blend of mystery, danger, and holiday atmosphere, Undercover Claus will grip you from the first page to the final snowfall. Perfect for fans of tense undercover thrillers, powerful sister bonds, and Christmas stories with a sharp edge.

Lena's trail isn't cold.
It's just beginning.
And so is this series.
