This is a short story, set in Scotland after global conditions change greatly. To a large extent, it's another of those "Survivor" scenarios, where folk have to cope with huge changes to climate/technology/whatever.
The story itself is interesting, the characters plausible, and MacLeod's possible future is, in my opinion, possible, and is also consistent within itself.
Where this slim volume falls down most is in value for money. The story is spread over 77 pages, yet the book costs only a pound less than a full-sized MacLeod novel with five times the page count. You can easiy read it in an afternoon.
Without giving away the plot at all, the ending seems to lack the obvious retribution that should occur. I hope that the "Happy ever after" hollywood plot endings are not going to occur in MacLeod's work from now on.
