40K is a new company based in Italy publishing e-books in English, some originally written in English and some in translation. So far they've only published short-form fiction in the form of novellas. I tried three of them out - Wikiworld, by Paul di Filippo, The Wooden Baby, by Graham Edwards, and If By Reason of Strength by Jamie Rubin.
They cost £2.49 each on the Kindle, and cost is the problem. All three were decent shorts, but they're too expensive. At no more than a quarter of the length of a typical novel, they are a lot more than a quarter of the price, making them poor value for money by comparison. Things look even worse when you compare the price to that of a magazine like Analog or Lightspeed, both of which come out monthly for £1.99 and typically contain one or two novellas plus several shorter stories as well as factual articles and book reviews.
At half their current price, I'd take the time to actually review the stories properly and probably give them quite high marks. At their current price, I won't bother buying any more of them.
