Romina Russell Books in Order

Sixteen-year-old Rhoma Grace becomes Guardian of House Cancer after a devastating attack. Believing an exiled thirteenth figure threatens the Zodiac, she travels between its divided planetary houses, hoping to persuade their leaders to unite before further destruction follows.

Disgraced and working in a refugee camp, Rho hopes to leave leadership behind. Threats from the Marad and a cryptic message pull her back into conflict, sending her across unfamiliar Houses to protect the Zodiac Galaxy.

An uneasy peace follows the Marad's disappearance, but Rho suspects the enemy remains active. Traveling through the Zodiac Galaxy, she investigates a rising political movement and visions of her mother while searching for the concealed Master.

With the Master exposed and her loved ones threatened, Rho faces a struggle against an enemy determined to rule the Zodiac Galaxy. The young Guardian must decide how to keep fighting when the odds appear overwhelming.
