The only clue Joe has about his identity is a century-old postcard of a Scottish lighthouse that arrives in London the same month he does.

In the process, Joe will remake history, and himself.

For one thing, genetic errors have crept in with each generation. For another, the original three clone "brothers" have gone their separate ways, and the branches of the family are now friendly rivals more than allies. Or maybe not so friendly.
