The official launch of To Raise the Fallen is next Thursday, but it is on sale now. Physically it is available in the Veritas main store in Dublin, and, I assume in other Veritas stores nationwide. It will also be available in other mainstream bookstores in Ireland. I am unsure about the arrangements for physical sales in other countries; perhaps that will follow in time. However, it can be ordered online and sent anywhere worldwide via the following link: http://www.veritasbooksonline.com/to-raise-the-fallen-a-selection-of-the-war-letters.html
I will publish a post very soon outlining the nature and contents of the book.
