How to Read Cassie Ryan's Books: The Recommended Starting Point
Cassie Ryan (the erotic romance pen name of author Tina Gerow) has built a dedicated following by writing books that are high-heat, humorous, and packed with paranormal elements or contemporary intensity. Because her stories are divided into distinct series that do not overlap in terms of continuity, you have two primary options for where to start, depending on your preferred romance subgenre:
- For Steamy Paranormal Romance: Start with Ceremony of Seduction (2007). This is the first book in the Seduction series, which introduces a rich, original world involving an extraterrestrial race that feeds on sexual energy. Reading this trilogy in order is highly recommended to follow the overarching world-building.
- For Contemporary Erotic BDSM Romance: Start with My Obsession (2015). This kicks off the Club Desire series, set in a high-end Phoenix BDSM club, and can be read independently from her paranormal books.
Below is a complete breakdown of every series in Cassie Ryan's bibliography, detailing their publication orders, premises, and chronological continuity.
1. The Seduction Series (Klatchian Trilogy)
Published by Kensington's Aphrodisia line, this paranormal romance trilogy focuses on the Klatchians—an otherworldly race from the planet Klatch whose life force and cosmic powers are sustained by sexual energy. The series blends science fiction, psychic connections, dream-walking, and high-heat romance. It should be read in strict publication order to appreciate the progression of the Klatchian lore and planetary conflict.
- Ceremony of Seduction (2007): Introduces Alyssa Moss, a woman on Earth who has always felt out of place. She is sought out by Stone, a warrior from the planet Klatch who has been visiting her dreams. When Stone arrives on Earth to claim her, Alyssa must decide whether to embrace her destiny.

2. The Sisters of Darkness Series
Stepping away from science fiction and into dark urban fantasy, the Sisters of Darkness series delves into demonic forces, archangels, and succubus mythology. The series follows succubus sisters working to fulfill their soul-harvesting quotas for Lilith, the Queen of the Underworld, only to find themselves falling for the men they are supposed to seduce.

- Sleeping with Shadows (2021): This novel centers on Matt Martin and Sarah Ryan. Matt is plagued by vivid, realistic dreams of a past-life love, leading him to investigate a cosmic mystery. As they reunite, they must stop a vengeful ex-lover from disrupting universal karmic harmony and putting millions of lives at risk.
What to Know Before You Start: Pseudonyms and Cross-Reads
Cassie Ryan is the pen name of Tina Gerow. The author reserves the Cassie Ryan name specifically for her erotic romance, high-heat paranormal romance, and BDSM titles.
