"Mary Roach has written about corpses (her description of severed heads sitting in dog bowls awaiting the steady hands of plastic surgeons will never leave me), shitting in space (look up "fecal decapitation"), orgasms (check out that TED Talk for info on recipes for semen and ancient greek orgasm theory), and she does it all with a clear eye and a dry humor," Rich Smith has noted. Join her tonight for a live Seattle Arts & Lectures talk online, where she'll be chatting about her forthcoming book about the often fraught encounters between animals and people.
