I picked up Runemarks only knowing that I loved the author's previous adult novels (particularly Five Quarters of the Orange which haunts me to this day). Now you wouldn't think a highly successful writer who usually writes historical novels set in the French countryside would suddenly come out with a fantasy book for teens all about Norse gods and the mortals and goblins who get wrapped up in their dealings. But you'd be wrong. This was a fun read. Odin and Loki and several other familiar names show up. However, you don't have to be familiar with Norse lore to enjoy this one at all. I'm giving this one a 6.
