CrimethInc. books are a good, very empowering start. They make revolution taste like happiness. 

Days of war, nights of love (Crimethink for beginners), CrimethInc. Free Press, Canada, 2001, is a theoretical, political statement, in the shape of a malicious and provocative piece of art. You will feel the urge for action after reading it. A little quote to get you started.

Their Recipes for Disaster (an Anarchist Cookbook), CrimethInc. Workers' Collective, Olympia, 2005, are advice for everything, that you are strongly advised not to follow! they range from very joyful recipes (parties, love), to very serious ones (sabotage), with D.I.Y. useful stuff (screenprinting, media), practical info (coalition building, legal support), day time mass actions (Food Not Bombs) and night time secret ones (billboards improvement), funny (painting a bicycle) to less funny (supporting survivors of domestic violence) activities... From love to war, and back.
