Necroville [EPUB ebook] 

In the Los Angeles ghetto of Necroville, the yearly celebration of the Night of the Dead – where the dead are resurrected through the miracle of nanotechnology and live their second lives as non-citizens – becomes a journey of discovery and revelation for five individuals on the run from their pasts. With his customary flair for making the bizarre both credible and fascinating, Mc Donald tosses aside the line of demarcation between living and dead in a story that confronts the central quandary of human existence: the essence of non-being.
