The Drowned Kings Return. The lightkeeper chronicles, #4

Christmas should be a season of warmth and ordinary magic. But when an ancient crown rises from the Mersey, Clara's quiet holiday is pulled into a story far older than she ever imagined. Calder is still haunted by the memories the river stole from him, and the boy at the docks watches from the shadows, waiting for Clara to understand what she's truly carrying. As Christmas settles over Liverpool - carols in the streets, lights in the windows, the city wrapped in winter - old echoes stir beneath the surface.
Lost kings, broken promises, and a truth the river has guarded for more than a century begin to rise. The crown is calling.  The river is remembering.  And Clara is running out of time. Book Four of The Lightkeeper Chronicles brings the mystery to its most haunting Christmas turning point.
