Six months ago, the Whisper began. Every thirty minutes, the same woman's voice echoes through the minds of four brothers. "Come to me... Obey." Danny, Marcus, Caleb, and Noah Sato have spent their lives running toward emergencies-a paramedic, a firefighter, an ER nurse, and a 911 dispatcher serving Charleston, West Virginia. They know how to save lives. They know how to face the worst days of other people's lives. Then the impossible begins. Someone from their past reappears, offering answers in exchange for their help on a mission that may very well cost them their lives.

In Orvatka, Isabella has forged a new life in a hidden mountain village, raising her twin children in the heart of a foreign tribe.

Haunted by secrets and bound by loyalty to a powerful leader who values her knowledge, Isabella's journey becomes a delicate balance of survival, self-discovery, and love. As tensions rise and hidden truths come to light, she must decide how far she's willing to go to protect her children and face the life she left behind.
