Etsy seller Dellamorteco's $250 kraken bookends are made of resin and hand-painted; they're beautiful (as are his Tentacle Candlestick Holders). My only concern is that the resin might not be heavy enough to hold the books in place -- I've lost some beautiful bookends when they were pushed off the shelf and to the floor far below.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
