This is an interesting piece of speculative fiction in which humans hibernate in winter. Set in Wales, it follows Charlie Worthing as he joins the Winter Consuls, a group of folks who elect to change their hibernation period so that they can be up during winter to look after the people regularly hibernating. In this world, a company has patented a drug that allows people to hibernate without dreams, which has helped people make it through the hibernation period in greater numbers, which has been great for society. The downside is, a small number of people wake up from hibernation with the drug as nightwalkers, essentially brain dead (and often violent) but sometimes with enough function to be trained to do odd jobs. Charlie has to survive his first winter solving a mystery, facing villains, and avoiding fairy tale WinterVolk.
This was really entertaining. I enjoyed the world that it was set in (and, I’m always here for books set in Wales that implies that all of the community is primarily Welsh speaking). I liked the exploration of what it would be like if humans hibernated. That was really interesting. There were a few conceits that did not work for me, but in general this book was an excellent escape from reality.
