Dear Reader,
Thank you for buying this book. You may have noticed that it is free of Digital Rights Management. This means we have not enforced copy protection on it. All Tor ebooks are available DRM-free so that once you purchase one of our ebooks, you can download it as many times as you like, on as many e-readers as you like.
We believe that making our Tor ebooks DRM-free is the best for our readers, allowing you to use legitimately- purchased ebooks in perfectly legal ways, like moving your library from one e-reader to another. We understand that DRM can make your ebooks less easy to read. It also makes building and maintaining your digital library more complicated. For these reasons, we are committed to remaining DRM-free.
We ask you for your support in ensuring that our DRM-free ebooks are not subject to piracy. Illegally downloaded books deprive authors of their royalties, the salaries they rely on to write. If you want to report an instance of piracy, you can do so by emailing us: anti-piracy@macmillan.com.
Very best wishes,
The Tor UK team & our authors
To all you steady researchers and developers of our technology,
for recognizing the optimistic road to the future,
rather than seeing a slippery slope to doom.
