Dexter Is Dead (Dexter 8)

He is in prison on multiple homicide charges, although, ironically, he did not commit any of the murders of which he is accused. He’s lost everything: his wife, kids, career, and the loyalty of his sister. Now his sole, small shot at redemption may come from his brother, Brian, a homicidal maniac who makes Dexter look like the angel in the family. By helping Brian through some serious trouble of his own making, Dexter sees a potential path to proving himself innocent.
 
But the stakes are truly deadly. And, with nothing left to hold him back, Dexter hurtles into an epic showdown ... which may be his last.
