Nigerian author Ayobami Adebayo's debut novel Stay with Me has been long-listed for a British literary award, the Wellcome Book Prize.

Adebayo, 30, is the only African on the long-list of 12 for the £30,000 ($42,000) award.

The New York Times described Stay with Me as a "stunning debut novel", while its publishers say it is "the heart-breaking tale of what wanting a child can do to a person, a marriage and a family; a powerful and vivid story of what it means to love not wisely but too well".
