The Valkyries are a force to be reckoned with-warrior women who roam the Mojave desert on motorbikes, leather-clad despite the heat. But they are also spiritual beings and it is to them that Paulo Coelho is led in the search for his own guardian angel.

For forty days and nights Paulo and his wife travel with the Valkyries, battling against fear and self-doubt and working to conquer the dark weight of the past pressing on Paulo’s shoulders. But will he end up destroying the things he loves the most in the world?
