Ambigrams, or inversions, are graphical figures that spell a single word in multiple directions or orientations. There are a number of categories, including rotational ambigrams, which present several instances of a word when rotated through a fixed angle, and mirror ambigrams, which can be read when reflected in a mirror. The word â€œsunsâ€ is a natural ambigram, meaning it has some form of symmetry in its natural state. What novel, published by bestselling author Dan Brown, features ambigrams?
