“Inventive and solidly enjoyable… Schroeder paints his unique world with deft touches while keeping the story moving briskly.” —Publishers Weekly, on The Sunless Countries

“I loved it. It never slowed down. The background is fascinating and the characters held my attention. It reminded me a little of The Integral Trees, with technology a little more advanced.” —Larry Niven on Sun of Suns

“Schroeder...is proving to be one of our most ingenious devisers of exotic, fantastic settings as well as a spinner of ripping yarns....Schroeder's world-building, storytelling, and character-drawing chops seem strong enough to give even Known Space a run for its money.” —Locus on Queen of Candesce

“[The] world-building continues to be impeccable, and the story's timing is a fantastic tour de force of his creation. The politics and structure of Virga continue to be a fine backdrop to some of the most entertaining space opera out there.” —Booklist on Pirate Sun

“Ashes of Candesce brings the Virga saga to an operatic, crashing finale; a splendid climax to the hard SF saga of the decade!” —Charles Stross on Ashes of Candesce

“A delight, a source of seemingly endless invention….” —Locus on Pirate Sun

“With Queen of Candesce, Karl Schroeder's Virga saga establishes itself as an SF saga of the same order as LeGuin's Earthsea series, Asimov's Robot stories, and Niven's Ringworld stories.” —SFRevu

“A fantastically alchemical tale set in a strange yet utterly real world. Hayden is a complex and well-developed protagonist and Schroeder is a amazingly detailed writer whose world-building is superb.” —RT Reviews on Sun of Suns
