All Together Dead is the the seventh book in Charlaine Harris's series The Southern Vampire Mysteries. After being betrayed by her vampire love, Bill Compton, Sookie Stackhouse attends an all-important central U.S. Vampire Summit on the shores of Lake Michigan as a "human geiger counter" for Sophie-Anne Leclerq, Vampire Queen of Louisiana and who will be tried during the event for murdering her husband, King of Arkansas. The summit is a tense situation. The queen is in a precarious position, her power base weakened by hurricane damage to New Orleans. And there are some vamps who would like to finish what nature started. Sookie knows the queen is innocent, but she's hardly prepared for other shocking murders, not to mention protests by the Fellowship of the Sun, a right-wing antivampire movement. Sookie's bond with Eric Northman gets closer and she discovers Quinn's past.
