Who Killed the Robins Family?

Rating:
Summary: Interesting spin on the mystery genre
Review: This novel has an interesting concept in that characters are killed off but the reader doesn't know who by. The authors held a contest at the time the book was published whereby readers could submit entries on who they thought the killer(s) were and they could win $10,000. I recently finished the book and now I am going to sit down and try to figure out who the killer(s) is(are). Doing the story this way makes the reader a little more involved in the book in that they have to figure who did it and why. I recommend this book to mystery readers and people who like puzzles as well.
