When she first tested it on a ridge above the clinic, the radio signal came in like a remembered voice—steady, clearer than any commercial solution had produced in months.

Lately she’d been haunted by a problem: in the valley outside the city, the emergency radios for remote clinics kept dropping out. The official fix—more towers, more power—was expensive and slow. Mira wanted something quieter, elegant. She wanted to listen. When she first tested it on a ridge
