"Standing there at Powell's grave, telling my nephew about a buried skull, I realize how much of our relationship revolves around body parts and severed heads. Once Owen learned to walk, we started playing a game I call Frankenstein, in which I am Frankenstein's monster and I chase him around trying to harvest his organs and appendages because my master is building another boy. "Frankenstein needs your spleen," I yell, aping the voice of an announcer at a monster truck rally. "Give me your spleen!" Which is why the seemingly gross book I gave him for his birthday, a collection of poetry for children called The Blood-Hungry Spleen was actually a sentimental choice, even though my sister tells me it didn't go over so well when he brought it to preschool."
