Six writers with "a passion for individual sensibilities" have been shortlisted for the 2019 Swansea University International Dylan Thomas Prize.
The shortlisted books comprise of five novels and one collection of short stories.
It is the 11th year of the world's largest literary prize for young authors writing in English and is worth £30,000.
The winner will be announced on 16 May.
Three of the nominees, Nana Kwame Adjei-Brenyah, Guy Gunaratne and Novuyo Rosa Tshuma were selected for their "powerful and challenging works" on race, immigration and post-colonial history.
They are joined by Louisa Hall with her novel on the father of the atomic bomb Robert Oppenheimer, Zoe Gilbert and her folkloric tale of the fictional village of Neverness, and Sarah Perry with her latest bestseller.
Prof Dai Smith, who chaired the judging panel, said the shortlist had "uncovered a wealth of new talent representing a group of contemporary and diverse voices from across the world".
"They are linked by a passion for individual sensibilities against a backdrop of history; sometimes violent, always life changing," he said.
