Another Book I Wonder Why I Wanted to Read

I finished The Love Curse of the Rumbaughs, by Jack Gantos last night. What a strange - no, creepy story. It's gothic in an old-fashioned sense, with the curse being something repulsive that we watch the narrator rationalize. It's gripping, and the writing is strong, but I can't imagine recommeding it to any of my lib patrons. And, I wonder, again, where I read about it -- what end of the year list, what passing mention made me want to call it from another branch and read it. Should I start noting the source when I Shelfari something as "want to read"?
