A "dazzling" tale of empire and betrayal set among the stars (#1 New York Times bestselling author Casey McQuiston), this queer, spectacular space opera draws inspiration from Roman and Egyptian empires—and the lives and loves of Cleopatra and Julius Caesar. Princess Altagracia has lost everything. After a bloody civil war, her twin sister has claimed both the crown of their planet, Szayet, and the Pearl of its prophecy: a computer that contains the immortal soul of Szayet’s god. So when the interstellar Empire of Ceiao turns its conquering eye toward Szayet, Gracia sees an opportunity. To regain her planet, Gracia places herself in the hands of the empire and its dangerous commander, Matheus Ceirran. But winning over Matheus, to say nothing of his mercurial and compelling captain Anita, is no easy feat. And in trying to secure her planet’s sovereignty and future, Gracia will find herself torn between Matheus’s ambitions, Anita’s unpredictable desires, and the demands of the Pearl that whispers in her ear. For Szayet’s sake and her own, she will need to become more than a princess with a silver tongue. She will have to become a queen as history has never seen before. "A glittering triumph of a book that weaves together history and tragedy into a star-spanning epic." —Everina Maxwell, author of Winter’s Orbit

Stars of Empire is a role playing game in which the Victorian Powers have discovered space flight and are striking out across the vast darkness of interplanetary space. As they explore frontiers on Earth, Luna Mars and Venus they encounter transplanted populations of humans, ancient and terrible alien races and ferocious exotic beasts, until 1892 each considered the other Great Powers to be their biggest rivals. It was in that year The Hive broke free in Devon and threatened more than just the balance of power on Earth. The Hive put the very existence of mankind at stake. Stars of Empire is a stand alone game book. It contains the core role playing rules, based on Black Pigeon Press' Hacktastic system and a detailed and dangerous universe setting. The Victorian in Our Time Line was a period of exploration and scientific achievement, military conflict and colonial conquest and social upheaval. In Stars of Empire aerial and space travel have been cleverly grafted into this historical fabric. Players will be able to interact on not only Earth but other worlds as well. Mars is home to a race of ancient aliens, powerful dangerous and unpredictable to the minds of men. Their true powers and purposes are shrouded in mystery. It is know that for many thousands of years they have harvested humans from Earth for use as slaves. With this human workforce Mars has been transformed from a lifeless rock into a tropical greenhouse of a world. Venus, beneath its thick atmosphere is a strange mix of dark basalt plains and humid cloud forests. Rules include character generation, combat and detailed sections allowing characters to develop engineering projects, scientific theories or inventions.

The Glory of the Empire is the rich and absorbing history of an extraordinary empire, at one point a rival to Rome. Rulers such as Basil the Great of Onessa, who founded the Empire but whose treacherous ways made him a byword for infamy, and the romantic Alexis the bastard, who dallied in the fleshpots of Egypt, studied Taoism and Buddhism, returned to save the Empire from civil war, and then retired “to learn to die,” come alive in The Glory of the Empire, along with generals, politicians, prophets, scoundrels, and others. Jean d’Ormesson also goes into the daily life of the Empire, its popular customs, and its contribution to the arts and the sciences, which, as he demonstrates, exercised an influence on the world as a whole, from the East to the West, and whose repercussions are still felt today. But it is all fiction, a thought experiment worthy of Jorge Luis Borges, and in the end The Glory of the Empire emerges as a great shimmering mirage, filling us with wonder even as it makes us wonder at the fugitive nature of power and the meaning of history itself.

Around a decade has passed since the Fall of Lahkfacar, and the Empire is now split into two distinct regions. Crown Princess and fleet commander Lafier is tasked with the operation to annex the People’s Sovereign Stellar Union and reunite the Empire while at the same time facing supply shortages and crew inexperience — and she might need to flout orders to get it done.
