Magical Cosmic collection Books in Order

The Magical Cosmic collection is Debbie Behan's biggest swing at space fantasy, romance, and mythology all at once. These books are not hard science fiction. They are more interested in gods, planets, destiny, loyalty, and emotional fallout than in technology. If that sounds like your kind of ride, this series gives you a lot to work with.

The collection begins with Cassandra Goddess of Harmony. Cassandra Wyatt starts out as an abandoned royal daughter whose dangerous powers make her an outsider in her own story. She is rescued by Kayden Hunter, commander of an elite group of universal peacekeepers called the Cloud Riders. That rescue does not solve her life. It only opens the door to a much larger world, one where personal history, magical ability, and political conflict are all tangled together.

The Cloud Riders are the thread that helps hold the series together. They move across the heavens on white horses and work to keep peace across the Home Worlds of the star systems. That gives the books their particular flavor. The scale is cosmic, but the mood is often intimate. Behan is just as interested in trust, attraction, jealousy, and emotional wounds as she is in battles or mythic lore. The result is a series that feels like a blend of fantasy quest, star-spanning adventure, and relationship drama. One especially unusual touch is that the world still carries an Australian feel, even while the action stretches into the heavens.

The focus then shifts toward Caitlin in Caitlin Goddess of Peace and Caitlin II Masquerade Magic. Caitlin is already part of the peacekeeping world, but her path is no easier for that. She is drawn into trouble through powerful men, divided loyalties, and threats that keep growing in scale. In the second book, her story turns on a rescue, a strange job, and a confrontation with Hades. In the third, wider political pressure builds around a dwarf planet kingdom, Earth itself is in crisis, and Caitlin is called to make choices that those around her may not like.

This is a feelings-forward series.

What carries across the books is the tension between power and belonging. These characters are not just trying to win fights. They are trying to understand who they are, where they fit, and what duty costs when love and friendship get mixed into the same decision. Behan also likes to place women at the center of that conflict. Cassandra and Caitlin both have to navigate worlds that are dangerous, romantic, and often unpredictable, without losing their nerve.

Readers should start in publication order, Cassandra Goddess of Harmony first, then Caitlin Goddess of Peace, then Caitlin II Masquerade Magic. That order lets the setting, the Cloud Riders, and the emotional stakes build naturally. Expect mythology folded into space fantasy, strong doses of romance, and a universe where peace is always fragile and every bond gets tested.
