Keepers Of The Lighthouse. The McTavish Chronicles, #3

On Tempest Island, some secrets were never meant to resurface. Coby McTavish returns to his ancestral island with Gracie and their newborn child, expecting a quiet inheritance. Instead, he is drawn into the shadowed legacy of Hotel Luminara - and the looming lighthouse where keepers vanished without explanation. As Coby begins to unravel the island's buried history, powerful forces take notice. Reed Winslow, a reclusive jeweller known as the Prince of Diamonds, has his own claims on Tempest Island's past.
Through the ruthless Ryder Blackwood, he will do whatever it takes to ensure those secrets remain hidden. Legends long dismissed as myth begin to stir. Ghostly apparitions, whispered names, and the tale of a cursed diamond - eerily reminiscent of the infamous Hope Diamond - draw Coby deeper into a dangerous pursuit across storm-lashed shores and crumbling estates. When tragedy strikes close to home and his family is placed in jeopardy, the race for truth becomes a matter of survival.
With history threatening to repeat itself, Coby must confront the lighthouse's final secret before it claims yet another life. Keepers of the Lighthouse is a dark, atmospheric gothic supernatural thriller of inheritance, obsession, and the cost of uncovering the truth.
