A ghost at the piano. A melody unfinished. A mystery that won’t stay silent.

When a ghost begins playing the piano at midnight in the dining hall of Beacon of Hope, Lois Grover knows the Twilight Society has another mystery on its hands.

The haunting melody belongs to Sigrid Swanson—a brilliant young pianist brutally murdered on a college stage in 1977. Her killer was never caught, and her restless spirit has spent decades searching for justice.

Determined to help the troubled musician find peace, Lois and her friends dig into the chilling cold case. Suspects include campus police officers, a troubled maintenance worker, and a charismatic actor whose connection to Sigrid may have been far darker than anyone suspected.

But the investigation isn’t the only mystery haunting Lois.

Deep in the Shenandoah Valley lies Pluto’s Gate—a strange cavern rumored to bend the laws of time itself. After discovering its power, Lois must confront a temptation that could change her own past forever…even as she works to solve Sigrid’s.

As the Twilight Society reaches out through séances and spirit boxes, long-buried secrets begin to surface—and one dangerous spirit will do anything to keep the truth hidden.

To free Sigrid’s soul, Lois and her friends must uncover what really happened on that lonely stage all those years ago.

Because some melodies refuse to end until justice is finally heard.
