Nigerian writer anietie isong emerge winner of 2018 mckitterick prize

I think there may be a mistake here!

After conducting a quick search, I couldn't find any information that suggests Anietie Isong, a Nigerian writer, won the 2018 McKitterick Prize. The McKitterick Prize is a literary award given annually by the Society of Authors in the UK to recognize a debut novel by a writer over the age of 40.

If you could provide more context or clarify which Anietie Isong you are referring to, I'd be happy to help you find the correct information.
