Ferréz (Reginaldo Ferreira da Silva) (born 1975) is a Brazilian author, rapper, cultural critic and activist from Zona Sul (Southern Borough) favela of Capão Redondo in São Paulo, Brazil.

He emphasises that his writings are addressed to the youth that live in the slums, so that they feel a sense of pride in reading literature that reflects their reality and experiences.

[2] Ferréz, whose real name is Reginaldo Ferreira da Silva, was born in the Favela of Valo Velho on the southern outskirts of São Paulo in 1975.

He was nicknamed after two Brazilian folk heroes: the widely known Lampião (actually Virgulino Ferreira) from the northeast part of Brazil and Zumbi, the legendary slave leader.

The complexity in the novel is the overlapping and intersecting of each individual criminal's history to the present moment where the reader finds the group involved in activities ranging from robbery, hanging out at the club to intimate relationship with others.
