Absolutely ripping, finished it in two days and immediately ordered the sequel. My only complaint is that I need ALL the details of the marvelous setting. Not that the book is short on them or anything, but a feast of imagination flits by in the background of this story, and everything outside that world feels dull by comparison right now.
The characters feel perfectly genuine, except for the classic (and forgivable) genre exception of "I guess there's no time to force these strangers to explain these incredible developments, so I'll just go along with it." I also perceived a touch of the Mary Sue about the protagonist, but in this case I'm in favor of it. And, to my surprise and satisfaction, Nnedi Okorafor deftly dodges the vast majority of pitfalls that tend to plague the "yer a wizard, kiddo" theme. The core crew's varying relationships to their looming adolescence lends an enjoyable richness to their interactions, and I especially enjoyed the passing-without-comment displays of collective leadership and decision-making in action.
I'm expediting shipping on the next book and dropping this one off to a neighborhood eleven-year-old girl who will go bananas over it. Very excited to continue with this series and this author.
When I have the time to sit 'n read, I can't seem to put it down. Also, it's a fast read for me. I'm going to order "Akata Warrior" soon.
