Suggest me a book from Cameroon

Hi everyone I am looking for the best books from Cameroon for the Read the World challenge over at r/bookclub. The book can be any length, and genre but it must be set or partially set in Cameroon. Preferably the author should be from Cameroon, or at least currently residing in Cameroon or has been a resident of Cameroon in the past. I'm looking for the "if I could only ever read one book from Cameroon which book should it be" type suggestions.

Thanks in Advance

The book must be available in English
