Kalie Cassidy writes the kind of fantasy that feels like slipping beneath dark waters, mysterious, lyrical, and quietly dangerous. Her debut novel, In the Veins of the Drowning (2025), invites readers into a world of winged sirens, fractured kingdoms, and a heroine caught between survival and self-discovery. It is the first book in The Siren Mage series, a romantic fantasy steeped in political tension, cultural myth, and the raw pull of identity.

Cassidy grew up in Southern California, where the Pacific’s edge and her Puerto Rican and Irish heritage shaped how she saw the world, as both belonging and apart. Before turning to fiction, she spent over a decade in the theatre as an actor, coach, and teacher in Los Angeles. That background informs her storytelling: her characters speak with emotional honesty, her scenes move with a sense of stagecraft, and her prose lingers with the rhythm of performance.

The Siren Mage

In a world where the ocean hides more than secrets, The Siren Mage unfolds a haunting tale of power, identity, and forbidden bonds. The series begins with a siren named Imogen Nel, who conceals her wings and blood magic beneath the surface of a kingdom that fears her kind. When a blood bond forces her to ally with a brooding king, their desperate flight across waters haunted by the undead becomes a journey that blurs the line between survival and sacrifice.
