Two narratives, one set in 15th-century Italy and one in modern-day Cambridge, printed in random order so that half the copies start with one and half with the other. Smith's formal gambit sounds like a gimmick but produces a genuinely different reading experience depending on which half you get first. A novel about art, grief, and perception that practices what it preaches.

The case for it, the case against, and the rest of the canon open with Pro.
