DON'T GO HOME.
At first, Claire assumes it's a cruel prank. But the messages keep coming-warnings only Matthew should know, details from their marriage no stranger could possibly have, and photographs taken from inside Claire's own house.
Then other dead people begin calling.
When Claire discovers a long-buried research program known as Project Echo, she learns the truth may be far worse than a simple haunting. Decades ago, researchers discovered that certain phone lines could carry voices from the dead. What began as an experiment in grief and communication became something much more dangerous-something that listens, learns, and grows stronger every time someone answers.
The rules seem simple.
A reply opens the line.
A confession opens the door.
An invitation lets something through.
But as Claire is pulled deeper into a nightmare of impossible messages, duplicate identities, missing people, and loved ones who may not be as dead as they should be, she realizes the rules themselves may be part of the trap.
The thing on the other side does not just know the past.
It can see possibilities.
It can use grief.
It can wear the voices of the people you love most.
And it is waiting for one thing:
A reply.
DO NOT REPLY is a fast-paced supernatural horror novel about grief, identity, impossible choices, and the terrifying question of what might be listening every time we reach into the dark and hope someone answers.
