An automaton, a secret love story, a man and a woman who can never meet, and the fate of the warming world are all brought to incandescent life in this haunting new novel from one of the most admired writers of our time.
 
When Catherine Gehrig, a museum conservator and clock expert, finds out that her very married lover of thirteen years has dropped dead, she has keep her grief a secret. But with no outlet other than vodka, her sorrow is close to driving the hyper-rational Catherine mad. The only person who knew of their affair—her boss—tries to distract and rescue her by giving her a project that demands all of her attention: the reconstruction of an elaborate nineteenth-century automaton. In the crates containing its bits and pieces, Catherine discovers a series of notebooks written by Henry Brandling, who, in 1854, commissioned the extraordinary, eerie mechanical creature in an attempt to bring joy to his consumptive little son. Henry's is a personal account of his adventures in the wilds of Germany, a diary that brings Catherine unexpected comfort, fellow feeling and wonder. But it is the automaton itself, in its beautiful, uncanny imitation of life, that links Henry's life to Catherine's, as both are confronted with the miracle and catastrophe of human invention, and the body's astonishing chemistry of love and feeling.
