This Christmas, the season of joy turns into a terrifying game of revenge.

A man dressed as Santa is found murdered and shoved up a chimney—a meticulously staged scene straight out of a nightmare. Days later, another murder staged like a twisted Christmas display is discovered.

With every gruesome crime comes a taunting Christmas card bearing a hand-drawn snowflake... delivered directly to PI Martina Monroe's door.

Martina, fearless and unyielding, teams up with homicide detective Kate Maddox and crime reporter Natalie Sloane, whose articles on real-life Christmas tragedies have begun inspiring the killer's next acts—a sure sign he isn't just reading her stories. He's watching her.

As the killer's motives come into focus, one thing becomes terrifyingly clear: this isn't just revenge. It's a message.

Now, with the clock ticking toward December 25th, Martina and Kate must unmask a killer before the holiday turns deadly for them all.

Her Silent Night is a special holiday installment in the Martina Monroe series. It's a dark, chilling standalone Christmas thriller that is perfect for longtime fans and new readers alike.
