A ghost on the telephone. A murder in the making. A switchboard operator determined to answer the call.

Newly arrived in Manhattan, Lottie Engel dreams of building a better life while sending every spare penny home to her ailing mother. As a telephone operator, she's expected to connect calls—not overhear deadly secrets.

Then a ghost appears in her switchboard.

The beautiful young woman insists Lottie listen to a single telephone line. What she overhears is a murder plot already in motion... and discovers the ghost was its very first victim.

With a killer preparing to strike again, Lottie finds herself swept into a dangerous investigation alongside the colorful residents of her boarding house, a charming immigration lawyer fighting for justice, a spirited band of union organizers, and one very determined ghost who refuses to rest until the truth is uncovered.

As corruption spreads through Gilded Age Manhattan, Lottie must stop a ruthless conspiracy before more innocent lives are lost.

Because some voices refuse to be silenced—even after death.

Perfect for readers who love cozy historical fantasy, paranormal mysteries, found family, slow-burn romance, amateur sleuths, Gilded Age intrigue, and ghosts with unfinished business.
