And clearly you've all had time to read all the books listed in my last post - and I've been reminded of even more wonderful snowy reads by some of your comments - so here's another list!
"Moominland Midwinter" by Tove Janssen. I've just finished re-reading this for the nth time, and was yet again entranced. Moomintroll inexplicably wakes up during his family's long winter hibernation, and he can't get back to sleep. All alone in the dark, snow-covered house, he encounters the mysteries and terrors of winter, including the taciturn Dweller Under the Sink, the sadly ditzy Squirrel with the Marvellous Tail, and the frighteningly beautiful Lady of the Cold. To say nothing of the brash Hemulen in the ski jumper. And how wonderful are the pictures!
A lot of people reminded me of "The Dark is Rising" by Susan Cooper - a majestic blend of Celtic mythology in a modern setting as young Will struggles against the forces of the Dark. There is indeed a magnificent snowstorm in this book. And "The Once And Future King" by T.H. White; and indeed why not Thomas Malory himself with "Le Morte D'Arthur"? If you skip all the stuff about the Roman Wars (the 'battling averages' as White called them, with all that repetitive stuff about how Sir X 'rode a great wallop' at Sir Y and unhorsed him) the book is very readable. I first came across the real thing in an extract published in a BBC Radio schools programme magazine when I was about 8 years old. It was all about young Gareth coming to fight the Red Knight of the Red Launds, and I thought it was wonderful.
And how could I have forgotten Joan Aiken? "The Wolves of Willoughby Chase", and perhaps even better, "Dido and Pa", with the wolves running over frozen Hampstead Heath, and Hanoverian villainy afoot?
Perhaps fictional snow is better than the real thing?
