The Drowned Echo

After his estranged grandfather’s funeral, Alex Mercer receives a single inheritance: a crude brass ring that feels unnaturally cold. Trying it on unleashes a terrifying, water-based entity that haunted his grandfather to his grave. Now, stalked by a relentless supernatural presence and a mysterious organization that monitors the cursed, Alex is bound to the ring. He must unravel its deep-sea origins before he's pulled under by the same dark tide that claimed his family, discovering that some things, once salvaged, should have been left in the dark.
