Kalie Cassidy

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.
