Excerpt from Stone Mattress by Margaret Atwood, plus links to reviews, author biography & more

The front porch steps are sheer ice already. She sprinkles ashes on them from the zip-lock, then stuffs the bag into her pocket and proceeds down crabwise, one step at a time, holding on to the railing and hauling the wheeled shopper behind her with the other hand, bump bump bump. Once on the sidewalk, she opens the umbrella, but that's not going to work--she can't manage those two objects at once--so she closes it again. She'll use it as a cane. She inches out onto the street--it's not as icy as the sidewalk--and teeters along the middle of it, balancing herself with the umbrella. There aren't any cars, so at least she won't get run over.

On the especially sheer parts of the road she sprinkles more of the ashes, leaving a faint black trail. Perhaps she'll be able to follow it home, if push comes to shove. It's the kind of thing that might occur in Alphinland--a trail of black ashes, mysterious, alluring, like glowing white stones in a forest, or bread crumbs--only there would be something extra about those ashes. Something you'd need to know about them, some verse or phrase to pronounce in order to keep their no doubt malevolent power at bay. Nothing about dust to dust, however; nothing involving last rites. More like a sort of runic charm.

"Ashes, bashes, crashes, dashes, gnashes, mashes, splashes," she says out loud as she picks her way over the ice. Quite a few words rhyme with ashes. She'll have to incorporate the ashes into the storyline, or one of the storylines: Alphinland is multiple in that respect. Milzreth of the Red Hand is the most likely provenance for those spellbinding ashes, being a warped and devious bully. He likes to delude travellers with mind-altering visions, lure them off the true path, lock them into iron cages or shackle them to the wall with gold chains, then pester them, using Hairy Hank-Imps and Cyanoreens and Firepiggles and whatnot. He likes to watch as their clothing--their silken robes, their embroidered vestments, their fur-lined capes, their shining veils--are ripped to shreds, and they plead and writhe attractively. She can work on the intricacies of all that when she gets back to the house.

Milzreth has the face of a former boss of hers when she worked as a waitress. He was a rump?slapper. She wonders if he ever read the series.

Now she's reached the end of the first block. This outing was maybe not such a good idea: her face is streaming wet, her hands are freezing, and meltwater is dribbling down her neck. But she's underway now, she needs to see it through. She breathes in the cold air; pellets of blown ice whip against her face. The wind's getting up, as the tv said it would. Nonetheless there's something brisk about being out in the storm, something energizing: it whisks away the cobwebs, it makes you inhale.

The corner store is open 24/7, a fact that she and Ewan have appreciated ever since they moved to this area twenty years ago. There are no sacks of ice melt stacked outside where they usually are, however. She goes inside, trundling her two?wheeled shopping bag.

"Is there any salt left?" she asks the woman behind the counter. It's someone new. Constance has never seen her before; there's a high turnover here. Ewan used to say the place had to be a money?laundering joint because they couldn't possibly be making a profit, considering the low traffic and the state of their lettuces.

"No, dear," the woman says. "There was a run on it earlier. Be prepared, I guess is what they had in mind." The implication is that Constance has failed to be prepared, which in fact is true. It's a lifelong failing: she has never been prepared. But how can you have a sense of wonder if you're prepared for everything? Prepared for the sunset. Prepared for the moonrise. Prepared for the ice storm. What a flat existence that would be.
