The second installment of the bestselling Zodiac series, a breathtaking astrology-inspired sci-fi saga.

“Russell’s excellent writing has only gotten better: her descriptions are deep and lush, her heroes fully formed and sympathetic.”—Booklist

“A thematically powerful ride.”—Kirkus Reviews

Orphaned, disgraced, and stripped of her title, Rho is ready to live life quietly as an aid worker in the Cancrian refugee camp on House Capricorn.

But news has spread that the Marad—a terrorist group determined to overturn harmony in the Galaxy—could strike any House at any moment. Then Ochus appears to Rho, bearing a cryptic message that leaves her with no choice but to fight.

Now Rho must embark on a high-stakes journey through an all-new set of Houses, where she discovers that there’s much more to her Galaxy—and to herself—than she could have ever imagined.
