Well hmm. I'd have to say Days Of War Nights Of Love by Crimethinc. But i had it as an audio book so I'm not sure if that counts.. Aside from that it would be The Most Beautiful Word In The English Language Is: Resist by Ellen Marie Hinchcliffe, though I love her poems in the book I have to say that some of the stuff she had to say, in a normal manner really struck me. There is such a risk taken for an anarchist to speek about romantic love, and she ( he? she had a sex change ) tackled that head on.
