This very beautiful biographical work on the Curies is also an artist's book, with every page filled with artistic imagery drawn by the artist. It has been characterized as part history, part love story, part artwork. It has also been characterized as "visual non-fiction."  Most of the images in the book are cyanotypes in a wide variety of colors. Another remarkable feature of the book is that it was typeset in Eusapia LR, a typeface created by the artist.
