I really like the books I’ve read by Adam Roberts. I’ve just finished his book called The Snow. The basic premise of this book is simple enough. It starts to snow. It continues to snow. Everywhere on Earth. For a long time. This continues until the snow is several kilometers deep and everyone except for about 150,000 people are dead. The survivors were mainly related to the military and their bases, are snow experts who were skiing in The Alps (for example), or have been dug out of buildings under the deep snow by the new Food Miners who dig down to get resources.
The story is told from the perspective of 2 main characters whose paths cross a few times, and also by the device of government memos and reports. Early in the book there is an explanation of how it is possible for so much snow to fall. I don’t want to say anything more about that as it’d be a spoiler for anyone who wants to read the book. The ending wasn’t what I was expecting from the early and middle sections of the book. If you like character driven sci-fi you should check this out.
BTW Adam Roberts also writes comedy books under the pseudonym A. R. R. R. Roberts. For example The Soddit.
