Uwem Akpan: The New Kid On The Block.

He only has the one book and it is pretty good. It is an anthology of short stories and the title of the book is taken from an instruction given by a mother to her daughter in the 2007 Caine Prize shortlisted story called "My Parents' Bedroom" which was published in the prestigious 'The New Yorker' Magazine. He has another story in the Newyorker too titled "An Ex-Mas Feast". You can read them both online if you have no access to the book.
