Circle of Seven Books in Order

The Circle of Seven books move away from modern dragon-shifter territory and into darker historical fantasy. Set in the fourteenth century, the series opens in a brutal version of medieval Transylvania, where warlords, assassins, sacred duties, and old magic all collide. If Dragonfury is about hidden supernatural life in the modern world, Circle of Seven leans harder into castles, forests, temples, prophecy, and the political weight of bloodline and belief.

The first two books lay out the shape of the series. In Knight Awakened, Afina Lazar is a high priestess on the run from Vladimir Barbu, a warlord who needs her to secure his claim to the throne. The assassin sent after her, Xavian Ramir, is a killer who has spent his life obeying orders and is desperate for a way out. In Knight Avenged, the focus shifts to Cosmina Cordei, a powerful oracle, and Henrik Lazar, another assassin with a history he would rather outrun than understand. The couples change, but the larger world remains linked by faith, violence, and the struggle over who gets to control sacred power.

These books are darker and more quest-driven than they first appear.

The world behind the romance includes a magical order tied to the Goddess, ancient rites, holy cities, dangerous relics, and enemies who want to bend spiritual authority into political power. Women in this series often hold the keys to survival, not because they are symbols, but because their choices carry real consequence. The men around them tend to be fighters shaped by loss, training, and guilt. That combination gives the romances a strong redemption thread. Love matters, but so do conscience, duty, and the question of whether a violent man can become something else.

Setting matters a lot here. You feel the road underfoot, the pressure of siege and pursuit, and the weight of old stone everywhere the story goes. There are strong fantasy touches, including supernatural beasts and dragons, but the books do not float away from human stakes. Hunger for power, fear of betrayal, family grief, and the cost of survival stay close to the surface.

The tone is dramatic, adventurous, and a little more solemn than Callahan's dragon romances. There is still heat, but it sits alongside battle scenes, mystical lore, and long-running conflict. Readers who like assassins with consciences, capable heroines carrying dangerous knowledge, and fantasy worlds with a thick layer of history will probably feel at home here.

Start with Knight Awakened and keep going in order. Even when each book shifts to a new couple, the wider fight keeps moving, and the emotional stakes deepen as the world opens up. Circle of Seven is a good fit if you want Callahan's sense of action and romance, but in a setting shaped by swords, prophecy, and medieval darkness.
