Zusanna Northfire was born in Copenhagen in 1977 and lives in Denmark with her husband, and her dog named Charlie who regularly interrupts writing sessions. She has three grown children and one grandson. By day, she works as a Senior Project Manager in the financial sector. By night—and most weekends—she writes vampire romance that combines Scandinavian sensibility with unapologetic passion. The Tenthborn is her debut novel and the first book in The Tenth Gene saga.
