Dark Echo

Dark Echo is an unlucky boat. Despite this knowledge, Martin Stannard falls under her spell and prepares to sail her across the Atlantic with his wealthy father. But his lover Suzanne begins exploring the yacht's past. What she finds is terrifying.
Because this boat isn't just unlucky, it's evil. It was built for Henry Spalding, a soldier and sorcerer who committed suicide yet still casts his malevolent spell nearly a century after his death. Suzanne must uncover his last, terrible secret before Dark Echo destroys the man she loves.
