Dead Beat, the seventh book in the Dresden Files series by Jim Butcher, sees Harry Dresden, a wizard and private investigator in Chicago, facing off against one of his most dangerous foes yet - a powerful necromancer who has stolen an ancient book of spells.
Harry must race against time to recover the book and stop the necromancer from using its dark magic to raise an army of the dead and take over the city. Along the way, Harry is aided by his friends and allies, including his apprentice, Molly, and the zombie Tyrone, as well as new allies like Butters, a shy and unassuming medical examiner who gets caught up in the magical mayhem.
As Harry delves deeper into the mystery, he discovers that the necromancer is working for a powerful and malevolent entity known as the Black Council, which has plans to use the book's magic to unleash a great evil upon the world. Harry must not only stop the necromancer, but also unravel the Black Council's plans and prevent the impending apocalypse.
The plot is filled with suspense, action, and humor, as Harry faces off against zombies, ghosts, and other supernatural threats, and races against time to save the city and the world. Along the way, he also confronts his own personal demons and struggles with his feelings for his on-again, off-again girlfriend, Susan.
Dead Beat is a thrilling addition to the Dresden Files series, with a complex and engrossing plot that will keep readers on the edge of their seats from start to finish.
