Penn Cassidy has published thirteen standalone novels between 2020 and 2025, and since each one is independent, readers can start with whichever title catches their eye. The books lean into dark and fantastical territory, with names like Throne of Crimson, House of Monsters, and Caged Fae suggesting a taste for the supernatural and the grim. Dead End kicked things off in 2020, and Cassidy has kept up a steady pace ever since, releasing multiple books per year.
The most recent additions are Folklore and Blood on the Styx, both from 2025. Earlier entries like The Old Gods, Midnight Hollow, and The Sword & The Stone rounded out a productive 2024. Whether readers prefer something with a mythological flavor or a more horror-leaning setup, there is plenty to choose from across these thirteen titles.
