Brinecrown: The Sunken Hoard
Your treasure-hunter father is dead; you inherit his rotting house on Morrow Cay, where the town still whispers about the Bloodwake — a pirate fleet that sank into the sea caves four centuries ago with a cursed hoard: spend any of its gold and the curse ages you to death. A cartel, a demon-worshipping church, and a rival archaeologist are all digging for it, and so is a beautiful woman far older than she looks. The hoard can buy you a life or a grave — decide which before someone else spends it.
