Rosemary Sutcliff is, as the readers and commenters on this blog attest, an internationally read and respected writer for children aged 8 to 88, of historical novels and other stories. As well as being published in English for the UK and Eire, Australia, New Zealand, South Africa, US and Canada, and readers of English everywhere, I believe The Eagle of the Ninth or some of the so-styled ‘trilogy’ (The Silver Branch, The Lantern Bearers) are published or about-to-be published internationally in these languages:
