Native land - R.-A. Salvatore - book

I grew up in the heart of Shadow-earth, in the underground city of Menzoberranzan, helpless against the cruelty of my kin. Dark Elves, my brothers, why have you treated me so badly? What sulphurous pact have you made with evil?
My honor will therefore condemn me to wander endlessly in the labyrinths of our underworld - unless I should strike indiscriminately at friend and foe. Zaknafein, O my fellow man, O my father, show me the way!
