Summer's Nightmare starts out with Summer James cowering in front of Marie Laveau's tomb. Laveau was a midwife and a practitioner of Voodoo in New Orleans during the nineteenth century. Summer is calling on her. She needs her help to avoid the guns that can be heard throughout the cemetery.
Summer cuts herself, uses her blood to mark Xs on the tomb, then slumps down and wakes up in a hospital ward for the criminally insane. In the ward, she encounters friends and foes and gradually finds out more about herself, including why she is being held there. Summer has been accused of murdering her husband, whom she has always loved. But she has no memory of what happened.
This is a good read for people who enjoy psychological thrillers involving Louisiana Voodoo and spirits of the dead.
