Recently my second book got published. I wrote it for my father but I was late by a month :-((((. It's about celtic religious poetry and comprises translations and some commentaries. And I like the illustrations:
My father liked the first one very much, and cited a couple of the lyrics from it on several occasions. As you can see ;-), the title of the book reads "Celtic Cross", and you can order it through http://www.religijna.pl/product_info.php/cPath/35_45/products_id/2424 (assumed of course that you understand Polish!!!).
