Meg, or Megaera, is one of the Furies you probably read about in Greek Mythology. She's also been sitting on one of Sam Quinn's stools in The Slaughtered Lamb Bookstore & Bar since it opened, glaring into silence anyone who tries to strike up a conversation with her.     Sam, being Sam, eventually broke through Meg's walls and a tentative friendship grew-not a warm one, certainly. Meg doesn't do warm. She has, though, in a crisis situation, shown up to fight alongside Sam.     Until recently, that is.     Sam's getting more and more concerned about Meg's strange absences and then she and Clive receive a text that turns their lives upside down. Meg tells Sam and Clive it's their turn to help her...in Greece...in the Underworld.     Sam badgers her friend Stheno into coming with them. I mean, if you have to descend into Hades' realm, a Gorgon can be pretty handy.     Keep your fingers crossed. Things are about to get downright mythological around here.
