This is a pretty good sudoku book. The puzzles range from medium-difficult to very difficult (devilish). They're nicely created, and the addition of a "target time" to each puzzle makes for a nice challenge for skilled sudoku-ers.
My only complaint about the book is the "bang for your buck" value... only 101 puzzles for 10 dollars, whereas many books now are going for more like 400 puzzles for 10 bucks. Still, it's only 10 cents per puzzle, and considering that these are ALL difficult and there will be no skip-over puzzles for master sudoku-ers, it'll take a fair amount of time to finish the book, thus redeeming its price.
