The dead are still listening.
Someone is killing the people who remember.
On a hidden dial-up bulletin board called the ECHO CHAMBER, forty-seven strangers trade memories that don't belong to them. One grew up in Minnesota and woke up fluent in Russian. Another stepped outside one winter morning and felt an ice shelf under her feet. Some of them have stopped posting. One drowned in a bathtub after weeks of tasting seawater, and the dates of the deaths are spaced too evenly to be chance.
Sam Hadley hears the same signal they do. Twenty months ago, a dead Cold War satellite showed her a memory with her own face in it. In June 1998 she drives home to Cherry Hill, New Jersey, where her father finally tells her what the program made her from, and why the signal has never sounded like a stranger.
The signal is still counting down to midnight, December 31, 1999, and whoever is hunting its listeners is not finished. To find the killer, Sam has to work crime scenes that exist only inside other people's heads, while the memories in her own begin to bleed together and she stops trusting what she sees.
Resonance is book 2 of the Dead Signal trilogy, a sci-fi mystery thriller set in the summer of 1998 among modem handshakes, payphone check-ins, and bulletin boards that never advertised they existed. It can be read on its own, and book 1, Static, tells how the signal first found her.
