Inspired by the true life and loves of the Russian scientist, inventor and spy Lev Termen – creator of the theremin, this novel takes us from the glitz and glam of New York in the 1930s to the gulags and scientific camps of the Soviet Union. We learn Termen's story: his early days as a scientist in Leningrad, and the acclaim he received as the inventor of the theremin, eventually coming to New York under the aegis of the Russian state. There he stays, teaching eager music students, making his name, and swiftly falling in love. But it isn't long until he has fallen in with Russian spooks, slipping through the shadows of a budding Cold War, with cold-blooded results. He is imprisoned in a Siberian gulag and later brought to Moscow, tasked with eavesdropping on Stalin himself. Like Termen's own life, this book is steeped in beauty, wonder and looping heartbreak.
