She summoned him for luck. He wants her for eternity. An inventor and a star-born beast collide in this hauntingly dark romantic fantasy by USA Today bestselling author I.V. Ophelia.

In the bioluminescent, star-worshipping city of Astraea, inventor and occultist Lucia Fairfax harvests a particular currency from the shadows—luck itself—drawn from a dimension she calls the Otherside. But when her latest ritual fails and her husband dies tragically, her carefully cultivated fortune bleeds dry.

Lucia’s desperate to restore her power, but her next ritual goes catastrophically wrong, summoning something far more dangerous: Altair, a cosmic entity born of an ancient constellation. He is both human and not—impossibly seductive, unnervingly sentient, and the key to restoring what she’s lost: a way to the Otherside.

Crossing into Altair’s realm is the most dangerous thing Lucia has ever done—and the most irresistible. There, she unravels the intoxicating secrets of the Otherside, the disturbing truth about her abilities, and the terrifying depth of his hunger. But with each revelation, escape slips further from reach. Trapped between worlds, Lucia must confront a devastating reality: Love, desire, and ambition all have their price. And Altair is eager to collect.

I.V. Ophelia is the USA Today bestselling author of Fruit of the Flesh and the gothic vampire series The Poisoner. Born in small-town New England, she now haunts the streets of New York City, writing the most unhinged tales she can conjure. When not crafting deliciously dark gothic romance, she works as a full-time artist, hoards nineteenth-century gowns and antique furniture, dotes on her menagerie of pets, and plots her next literary transgression.
