Most sudoku books give you a number and a grid. Landmark Sudoku gives you a place.
Every puzzle in every volume is named after a real landmark and carries a short, researched, sourced fact about it — where it is, and why it is worth knowing. One theme per book, one difficulty per book, so you always know what you are picking up.
