FRIDAY: Death by Sudoku

Another Sudoku series. Liza Kelly used to be a mover and shaker in Hollywood, but needed some times to regroup in her personal life, so she went home to Oregon to write sudoku puzzles for the local paper. In the first book, she returns to California for a sudoku tournament, and reconnects with an old friend. His sudden and mysterious death pushes Liza into solving sudoku for something much more serious than a tournament.

I have read the first three books in the series so far and enjoyed all of them. In my opinion, this series requires more background knowledge of sudoku than the other series I reviewed, but the author does a good job of explaining things for newbies.
