(SPOILER WARNING)The idea of items that serial killers use containing a leftover "evil" power is a great idea. But Saul doesn't really use it much--he could have had the boys become "possessed" by the spirits of Lizzie Borden, Jeffrey Dahmer, Ed Gein, et al. But nothing really happens to the premise and the book concludes with "Lizzie" running amuck. (In fact, this was the real flaw in the book because the axe she was accussed of using was NEVER found.)And other than the subject matter, this is really a YA novel -- the main characters are teenagers and the secondary story -- "townies" versus the "summer boys" -- is merely filler and goes nowhere.Would have been much more interesting to see the ADULTS become slowly obsessed with the items. Again, interesting idea, just doesn't work.
