Yes, Sanctioned is now available in both paperback and Kindle.
The paperback can be ordered from any outlet in the world (in theory) or direct from Amazon.
If you order the paperback from Amazon.com you can get the Kindle version free.
Unfortunately, this offer is not available on Amazon’s regional sites. (Amazon’s decision, not mine.)
Eventually, you will be able to order the paperback direct from the author (hi!) but there is no stock available yet. Watch here for updates on that.
