Helpful Score: 5
By far the best of the sudoku series as yet. The author is getting much stronger with story lines and continuity. The only problem I balked at when reading is why males and females would have been at the same correctional facility, but that did not take away from the story much. I felt that Liza is finally getting her legs under her as a sleuth and the clue finds and solving are seemingly more believable. I still struggle with the placement of puzzles, not knowing if I should stop reading to work them out, but I can definitely say that the story was a good, quick read.
