Early Life & Background
Cassidy was born and raised in Southern California, according to her published author biography, and later developed a professional career in the Los Angeles theater world. She has described spending more than a decade working as an actor, coach and acting teacher before turning her attention toward fiction.
Her background has influenced the stories she writes. Cassidy has publicly identified herself as being of Puerto Rican and Irish descent, and she has discussed how her experience with mixed cultural identity influenced themes of belonging and identity in In the Veins of the Drowning. The novel incorporates elements of Puerto Rican culture alongside mythology, romance and dark fantasy.
Cassidy has also discussed beginning the project that eventually became her debut while caring for a newborn and working through the writing process over several years. Her account suggests that she learned much of the novel-writing craft independently before finding a publishing home.
Career Journey & Breakthroughs
Cassidy’s publishing breakthrough came with In the Veins of the Drowning, published by Little, Brown and Company in July 2025. The novel follows Imogen Nel, a hidden Siren living in a kingdom where her kind is feared and regarded as monstrous.
Imogen’s circumstances change when a neighboring king discovers her identity. Their relationship becomes central to a story involving magic, danger, political conflict and a growing romantic connection.
Cassidy’s interpretation of sirens is one of the book’s distinctive features. Rather than relying solely on the familiar modern image of mermaids, she draws from older mythology and builds a fantasy world around powerful Sirens and magic users. The result is a combination of dark fantasy and romance that has attracted attention from readers of the romantasy genre.
The book also attracted attention before publication. In a People feature about the novel, Cassidy discussed her Puerto Rican and Irish heritage and how aspects of her background informed the novel’s themes.
The response from readers has been substantial. At the time of writing, Cassidy’s Goodreads author page shows tens of thousands of ratings across her books, indicating a sizeable readership for The Siren Mage series.
Cassidy followed her debut with In the Wake of the Ruined, the second book in The Siren Mage series. It was released in July 2026 and continues the story of Imogen and Theodore as their personal relationship becomes tangled with larger threats facing their world.
Her books have also received endorsements from fantasy and romantasy authors including Rachel Gillig, Ava Reid and Allison Saft.
