Matteo Alacran was not born; he was harvested. His DNA came from El Patron, lord of a country called Opium -- a strip of poppy fields lying between the United States and what was once called Mexico. Matt's first cell split and divided inside a petri dish. Then he was placed in the womb of a cow, where he continued the miraculous journey from embryo to fetus to baby. He is a boy now, but most consider him a monster -- except for El Patr'n. El Patr'n loves Matt as he loves himself, because Matt is himself.

As Matt struggles to understand his existence, he is threatened by a sinister cast of characters, including El Patron's power-hungry family, and he is surrounded by a dangerous army of bodyguards. Escape is the only chance Matt has to survive. But escape from the Alacr n Estate is no guarantee of freedom, because Matt is marked by his difference in ways he doesn't even suspect.
