Who is more dangerous, supernatural foes or enigmatic allies? That's on Magnus' mind a lot while the thousand-year old "Chosen Warrior" deals with bikers, cartels, a Yaqui shaman, visitations, explosions, crashes, brawls, and the occasional gunshot wound. Being an Einherjar hiding out from Odin and his Valkyrie is hard enough without having to wonder who is on your side and who is just waiting with a knife for your back. To make matters worse, it's one of Odin's own immortal wolves that Magnus aka Mouse is sworn to rescue. This time, being tough, scrappy, and a fair hand with runic magic might not be enough.
