One of the wonders of digital publishing is that you get global distribution of your book. The barriers that used to exist to acquiring English books abroad (I know, I lived abroad for many years) have disappeared.
The Grand Mirage is immediately available as an ebook on Amazon in the UK, Germany, and now France. Through the distribution channels of Ingrams/Lightning Source, it will eventually be available as a paperback in the UK, Canada, Spain (!), Australia and New Zealand, and in ebook format in those markets as well.
The novel features a British hero, a German villain, and a story of the vanished Middle East that has universal appeal, so it's great that readers in these markets have a chance to acquire it quickly and easily.
