No return address.
No fingerprints.
No mistakes.
For nearly a decade, the FBI has failed to stop an anonymous correspondent whose handwritten letters predict murders with terrifying precision. Each envelope contains intimate details about a victim's final hours—information no one could possibly know.
When forensic document examiner Natalie Brooks joins the investigation, she notices something every previous detective overlooked. Hidden within the handwriting are microscopic variations that suggest more than one author has been writing the letters.
What begins as the hunt for a single serial killer quickly transforms into a labyrinth of coded messages, forgotten government files, and decades-old disappearances that powerful people desperately want buried forever.
To decipher the next letter before another innocent life is lost, Natalie reluctantly partners with a retired cryptographer whose career ended after exposing classified secrets. Together they discover that every murder is part of a larger story—one written long before the first victim died.
As the letters become increasingly personal, Natalie realizes the killer isn't merely predicting deaths.
Someone is writing her future.
The final envelope contains no victim's name.
Only hers.
And the date is tomorrow.
