1867, Ryazan, a Russian city in winter. Ten-year-old Konstantin, deafened by scarlet fever, dreams of flight - escaping to Moscow, fleeing to the silent stars. And his daring visions, pregnant with humanity's future, will take him further than anyone could believe.

Moving from wolf-infested forests to the brothels of Moscow, from village life to the wondrous Age of Steam, from appalling tragedy to the discovery of a great love, Konstantin tells the beguiling story of a man who imagined the unimaginable: turning the dream of space travel into a reality.
