The book "Immortal Castro and his Serbian kin" by Dragoslava Koprivica was promoted in Havana, on 14 August 2013, organized by the Cuban Institute of Friendship with the Peoples.

A literary critic Pedro de la Hosa spoke about the book, which was presented in the framework of the celebration of Fidel Castro's 87th birthday, in support of the "Five heroes" (Cubans convicted by the U.S.A. for subversive activities).
