A new "echo" calls real estate agent Sloane to a magnificent old school, now a grand hotel. But instead of the quiet hum of history, she's greeted by a chilling cacophony: children's laughter mingling with desperate screams of "Fire!" Here, a dozen innocent child spirits, led by the brave Thomas "Tom" Finch, are trapped, reliving the horror of a Christmas Eve fire in 1925.

Sloane quickly learns the hotel's charming "haunting" is a cynical cover-up. The fire wasn't an accident, but a deliberate act by Walter Croft, the school's janitor, to conceal his ruthless embezzlement. Worse, Walter's ghost, now a cold, oppressive presence, still haunts the hotel, desperately trying to silence the truth and clear his own name by subtly blaming Tom for the tragedy.

With Caleb, her steadfast contractor, unwittingly uncovering clues and a group of grieving descendants gathering for their annual memorial, Sloane races against time. She must confront Walter's lingering malevolence, piece together the forgotten details of the fire, and clear Tom Finch's name to finally bring peace to the innocent children and expose a century-old crime.

In this haunted hotel, some stories refuse to be forgotten, and some voices demand to be heard.
