Published originally in Britain as Chaga, this novel has too many pages and too little happening in them, and this rang the death knell for it for me. To make it worse, it's merely book one in a dilogy, which means it's a prologue. I so don't do prologues.
The story is supposed to be about an alien invasion after a fashion, whereby the aliens send a conversion process to planets they want to colonize, which spreads unstoppably and converts local organic material to reprocessed organic material. In short, these aliens are evil no matter how benign their aim might seem.
So this meteorite hits Africa and starts changing everything it touches and becoming ever more widespread. Never once do people think of nuking it for reasons which went unexplained in the portion I read - which admittedly wasn't much. If they didn't want to nuke it there are other ways, such as chemical treatments or burning. None of this seems to have been considered, although I did not read far beyond the point where this begins spreading.
From the reviews of others I've read, apparently even the author thought this story was too boring to pursue, so he felt compelled to turn this into a love story. Evidently he needed to validate his female lead, Gaby McAslin, with a man, and so he had her taken in hand by someone with the highly appropriate name of Shepherd! From that point onward, so I understand it became a love story and the spreading contagion was nothing but backstory. Go figure. I'm glad I quit when I did.
I skimmed here and there beyond the point where I quit reading properly and saw nothing about any change to the woman. The book cover artist appears to be as utterly clueless here as book cover artists typically are everywhere, which I why I pay little heed to book covers. There is no transformation which involved a woman growing butterfly wings so why the artist chose that remains a mystery. I saw two different book covers and both featured a female rear elevation. I can only guess this artist (or these artists) love painting women's asses. In each case though, her hair is entirely wrong since the novel informs us it's long: down to the small of her back. So this is yet another case where the artist hasn't even read the book, a situation which is otherwise known as bait and switch for those idiots who buy books to read based purely on their cover.
I cannot recommend this based on the sorry portion of it I read.
