A Marca das Runas

Blurb

Runemarks is a 2007 fantasy novel by Joanne Harris. The book was published on August 2, 2007, by Doubleday Publishing and is set in a world where the Norse gods still survive as outlaws, their powers diminished, while a new and more powerful religion, the Order, tries to wipe out magic from the world. Harris has stated that she was inspired to write the book due to her love of Norse mythology as a child, with the book being loosely based on a novel she wrote in her late teens.
The book was followed up with a 2011 sequel entitled Runelight.
