Some dates you never forget. This one… you may not survive.

Jack Bennett has it all—a loving wife, three beautiful kids, a successful engineering career, and a home in the suburbs. But everything changes the day he finds a strange card in his mailbox.

Save the Date
No sender. No stamp. No return address.
Just a single line of text: April 21st.

Jack brushes it off as a mistake—until another card appears. Then another. And with each arrival, the cracks in his perfect life begin to widen.

What begins as a curiosity soon spirals into obsession. The cards keep coming. Mistakes pile up at work. Jack’s sterling reputation begins to crumble. Friends grow distant. Paranoia sets in. Someone is watching... lying, manipulating him. Plotting something far worse than he could ever imagine.

April 21st isn’t a coincidence. It’s a deadline.

As Jack searches for answers, he uncovers a chilling plot of deception, manipulation, and betrayal that runs deeper than he ever feared. He’ll have to fight to protect his job, his family, and his sanity—before time runs out.

Because someone doesn’t just want to ruin Jack’s life.

They want to erase it.

Tick, tock.

A gripping psychological thriller for fans of Gone Girl, The Silent Patient, Behind Closed Doors, and You, Save the Date is a razor-sharp, twisted tale of paranoia, sabotage, and the terrifying realization that the greatest threat may be the person you trust most.
