In 2013, he was among the inaugural winners of the Windham-Campbell Literature Prizes, awarded by Yale University.  Steinberg’s books also include "Three-Letter Plague" ("Sizwe’s Test" in the United States), which chronicles a young man’s journey through South Africa’s AIDS pandemic.

Steinberg's 2015 book, "A Man of Good Hope", was described as "superb" by "Observer" reviewer Ian Birrell, who wrote: "On the surface, it is simply the biography of a lonely young migrant who dreams of a decent life, hardening his shell and hustling to survive in hostile human environments.  Yet it is really an epic African saga that chronicles some fundamental modern issues such as crime, human trafficking, migration, poverty and xenophobia, while giving glimpses into the Somali clan system, repression in Ethiopia and lethal racism in townships." Jonathan Kellerman (born August 9, 1949) is an American psychologist, and Edgar and Anthony Award-winning author of numerous bestselling suspense novels.
