Mara Voss makes a living finding the truth hidden inside recordings. But when a mysterious cassette arrives carrying the voice of her sister—dead for seven years—her carefully controlled life begins to unravel.

The message leads Mara to Bellwether House, an abandoned facility in Florida with sealed rooms, hidden passages, and a history someone has worked hard to erase. Inside, voices can be copied, memories manipulated, and trust turned into a weapon.

As Mara follows the evidence, she uncovers disturbing secrets about her sister’s disappearance and her own connection to Bellwether. Someone knows she is searching. Someone is using the voices of those she trusts to control her.

To discover what truly happened, Mara must return to the house that has been waiting for her.

Some voices should never be answered.
