Hey, this one was pretty good. This is the third volume of The Adventures of Nzumah, all written by Naa Korkoi Abotchi, and published by Matador - who were good enough to send me these complimentary copies.
I couldn't find much information on Abotchi, other than that she was born in Ghana and now lives in Harrow. "[My] series has been inspired by conversations with her grandmother," she writes in her author bio, "whose story telling was legendary and who has been a very important part of [my] life. She is still very much alive when I remember the stories every day."
