Both Cold and Turn Around Where Possible are free from Amazon from today, for five days. You can get them here.
I don't often blog about free promotions, because it would get a bit repetitive, but I'll make an exception this time, because it's conceivable that this could be the last occasion these will be free. I'm thinking about bundling them, with some other stories, into a new collection of short fiction, and withdrawing the standalone titles. The collection won't be free.
Get 'em while they're hot, is what I'm saying.
