Further to yesterday's announcement that Tor Books, the largest science fiction publisher in the world, would no longer use DRM on its ebooks as of this summer: now Tor UK, a sister company to Tor Books, has announced it will follow suit.

Tor UK, Pan Macmillan's science fiction and fantasy imprint, has announced today that it will make its ebooks DRM-free over the next three months.

"We know that this is what many Tor authors passionately want. We also understand that readers in this community feel strongly about this," says Jeremy Trevathan, Pan Macmillan's Fiction Publisher.

This decision has been made in partnership with our sister company Tor Books, an imprint of Tom Doherty Associates, LLC, in New York. Tor UK is consulting with its authors at the moment and will announce their plans in more detail in due course.
