Karl Schroeder is one of the new stars of hard SF. His novels, Ventus and Permanence, have established him as a new force in the field. Now he extends his reach into Larry Niven territory, returning to the same distant future in which Ventus was set, but employing a broader canvas, to tell the story of Teven Coronal, a ringworld with a huge multiplicity of human civilizations. Brilliant but troubled Livia Kodaly is Teven's only hope against invaders both human and superhuman who would destroy its fragile ecologies and human diversity. Filled with action, ideas, and intellectual energy, Lady of Mazes is the hard SF novel of the year

Young Rue Cassels of the Cycler Compact- a civilisation based around remote brown dwarf stars — is running for her life from her bullying brother, Jentry. Fleeing in a single person spacecraft, she spots a distant, approaching object, and stakes a legal claim to it. It is not the valuable comet she has hoped for, but something even more wonderful, a billion year-old alien starship. Permanence is the story of Rue's quest to visit and claim this ship and its treasures, set against a backdrop of interstellar intrigue and warring empires

Venera Fanning was last seen falling into nothingness at the end of Sun of Suns. Now, in Queen of Candesce, Venera finds herself plunging through the air among the artificial worlds of Virga, far from home and her husband, who may or may not be alive. Landing in the ancient nation of Spyre, Venera encounters new enemies and new friends (or at least convenient allies). She must quickly learn who she can trust, and who she can manipulate in order to survive. Survival isn't her only goal; with the powerful Key of Candesce in her hands, she can control the fate of the entire world of Virga, yet something even more pressing is driving her—the all consuming need for revenge

It is the distant future. The world known as Virga is a fullerene balloon three thousand kilometers in diameter, filled with air, water, and aimlessly floating chunks of rock. The humans who live in this vast environment must build their own fusion suns and “towns” that are in the shape of enormous wood and rope wheels that are spun for gravity. Young, fit, bitter, and friendless, Hayden Griffin is a very dangerous man. He's come to the city of Rush in the nation of Slipstream with one thing in mind: to take murderous revenge for the deaths of his parents six years ago. His target is Admiral Chaison Fanning, head of the fleet of Slipstream, which conquered Hayden's nation of Aerie years ago. And the fact that Hayden's spent his adolescence living with pirates doesn't bode well for Fanning's chances
