Blackwater is the saga of a small town, Perdido, Alabama, and Elinor Dammert, the stranger who arrives there under mysterious circumstances on Easter Sunday, 1919. On the surface, Elinor is gracious, charming, anxious to belong in Perdido, and eager to marry Oscar Caskey, the eldest son of Perdido's first family. But her beautiful exterior hides a shocking secret. Beneath the waters of the Perdido River, she turns into something terrifying, a creature whispered about in stories that have chilled the residents of Perdido for generations.

A princess of Spain, Catalina is only 16 years old when she sets foot on the shores of England. The youngest daughter of the powerful monarchs Ferdinand and Isabella, Catalina is a coveted prize for a royal marriage - and Arthur, Prince of Wales and heir to the English throne, has won her hand. But tragedy strikes, and Catalina, now Princess Katherine, is betrothed to the future Henry VIII.

When she arrives at the hall, shaken by an unsettling disturbance that occurred during her travels, she is greeted by the two children now in her care, Isabella and Eustace. There is no adult present to represent her mysterious employer, and the children offer no explanation. Later that night in her room, another terrifying experience further reinforces the sense that something is very wrong. From the moment Eliza rises the following morning, her every step seems dogged by a malign presence that lives within Gaudlin's walls.
