This was an apocalyptic novella where the human race is subjected to The Wasting. Everyone over 40 'wastes' and turns into a cloud of spores. Such clouds sometimes block out the sun.
The survivors are trying to get themselves organized while trying to avoid the leftover pets which have now turned into mutant-y monsters that roam the streets. I don't want to give away too much of the plot, but I did find it to be interesting. There were some parts of it that reminded me of the "Day of the Triffids", but some other parts were completely original and unique.
Unfortunately there were a few weird word switch things happening-wonder and wander were confused and a few other words as well. All in all, I enjoyed this story and I will read more from Mr. Woodhead.
