Within the glittering Hapsburg court in Prague lurks a darkness of which no one dares speak…

In 1606, the city of Prague shines as a golden mecca of art and culture carefully cultivated by Emperor Rudolf II. But the emperor hides an ugly secret: His bastard son, Don Julius, is afflicted with a madness that pushes the young prince to unspeakable depravity. Desperate to stem his son’s growing number of scandals, the emperor exiles Don Julius to a remote corner of Bohemia where the young man is placed in the care of a bloodletter named Pichler. The bloodletter’s task: cure Don Julius of his madness by purging the vicious humors coursing through his veins.

When Pichler brings his daughter Marketa to assist him, she becomes the object of Don Julius’s frenzied—and dangerous—obsession. To him, she is the embodiment of the women pictured in the Coded Book of Wonder, a priceless manuscript from the imperial library that was the mad prince’s only link to sanity. As the prince descends further into the darkness of his mind, his acts become ever more desperate, as Marketa, both frightened and fascinated, can’t stay away.

Inspired by a real-life murder that threatened to topple the powerful Hapsburg dynasty, The Bloodletter’s Daughter is a dark and richly detailed saga of passion and revenge.
