Toast is a collection of older short stories by Charles Stross. When it got really hard to find, he released Toast for free as a Creative Commons thing.
I was pointed to Toast by Ron Hale-Evans, who mentioned that he preferred older Stross to his newer stuff. I see where he’s coming from, but I’m not necessarily sure if the axis is older/newer or shorter/longer. The older and shorter works are definitely harder to digest. When they unwrap in your brain few days after you’ve finished, it’s quite a delight. On the other hand, I think his newer work sells better. I was going to try to pick a favorite story, but that’s pretty hard. Big Brother Iron is set in the 1984 universe, and the main character is a sysadmins.
