[1] Caio F., as he habitually signed his letters,[2] was born in Santiago do Boqueirão in the state of Rio Grande do Sul in 1948, and died in Porto Alegre in 1996.
He wrote short stories, novels, chronicles or crônicas, drama, and he also maintained throughout his life an extensive correspondence with other writers and artists, family and friends.
[3] In 1968, Abreu was put on the wanted list by the DOPS or the Departamento de Ordem Política e Social, a repressive branch of the Brazilian government that operated during years when the repressive military dictatorship was in power, but found refuge at the country estate of Brazilian writer Hilda Hilst, located near the city of Campinas, in state of São Paulo.
[5] In Os dragões não conhecem o paraíso (Dragons), his most famous book of short stories, the majority of characters are either gay or they act as if they are.
A number of literary critics have noted Abreu’s attempt to create a Brazilian queer identity using the figures of monsters or dragons.
[10] Abreu’s style of confessional literature captures his personal fears, hopes, sentiments and desires but, at the same time, his voice is both individual and collective.
[16] His novel Onde Andará Dulce Veiga was also made into a feature film, released in Brazil in 2007 and directed by Abreu's friend Guilherme de Almeida Prado.
