'Geoff Ryman's new novel is swift, smart and convincing. Air is a wonderful and frightening examination of old and new, and survival on the interface between'. – Greg Bear

'This is a liminal book: its characters are on the threshold of something new; their village is on the brink of change; the world is launching into a new way to connect; humanity, at the end of the novel, is on the cusp of evolution… its plot is exciting and suspenseful, its characters gripping, its wisdom lightly and gracefully offered, its language clear and beautiful. Like The Child Garden, Air is both humane and wise. This novel is such a village. I cannot recommend it highly enough. It becomes finer as I think back on it, and I look forward to rereading it. I only wish Ryman's work were more widely available and more widely read, as it deserves'.- Joan Gordon New York Review of Science Fiction

'Ryman renders the village and people of Kizuldah with such humane insight and sympathy that we experience the novel almost like the Air it describes: It's around us and in us, more real than real, and it leaves us changed as surely as Mae's contact with Air changes her. This amazing balance that Ryman maintains – mourning change while embracing it – renders Air not merely powerful, thought-provoking, and profoundly moving, but indispensable. It's a map of our world, written in the imaginary terrain of Karzistan. It's a guide for all of us, who will endure change, mourn our losses, and must find a way to love the new sea that swamps our houses, if we are not to grow bitter and small and afraid'. – Robert Killheffer, The Magazine of Fantasy and Science Fiction

'The wondrous art wrought in Ryman's Air shows some of its meaning plainly, calling forth grins, astonishment and tears. More of its meaning is tucked away inside, like the seven hidden curled-up dimensions of spacetime, like the final pages of the third book of Dante, beyond words or imagining high and low. Treasure this book'. – Damien Broderick, Locus
