Last Call Before Dawn

At 2:17 a.m., the city usually tells the truth. So when dispatch sends paramedic Mara Voss and her partner Leon Price to a hotel that's been condemned for years, she assumes it's a glitch — until the address keeps calling back. What starts as a phantom dispatch unravels into something Mara can't unhear: a trail of black-file patients, a hospital network with a credential that should be dead, and a partner with a debt from his old crew that he never mentioned. As the phantom calls escalate and the hacked monitors start telling their own story, Mara has to figure out who is using her ambulance as a delivery system before dawn — and before whatever is moving through the hospital's devices finds its next patient. THE LAST CALL BEFORE DAWN is a breakneck medical thriller about the calls that shouldn't exist, the systems we trust blindly, and the partner you don't know you can't trust until it's almost too late — for readers of tech-conspiracy thrillers with a pulse.
