Several thousand years from now, advanced humanoids known as the Makers will implant clockwork devices into our heads. At the cost of a certain amount of agency, these devices will permit us to move unhindered through time and space, and to live complacent, well-regulated lives. However, when one of these devices goes awry, a "clockwork man" appears accidentally in the 1920s, at a cricket match in a small English village. Considered the original cyborg novel, and perhaps the original singularity novel, too.
