Isabelle Graw's latest book reflects on the purposes and struggles of friendship in competitive social milieus. By focusing on her own social milieu--the art world--Graw demonstrates how friendships are neither totally disinterested nor reduceable to their use. Written in the intimate form of a fictional diary, this book laments useful friendships while praising true friendship in all its forms. For Graw, friendship is an existential necessity--if only because it points to how we relate to and depend on others. Friendship, she finds, is as important as the air we breathe--with it, we are able to fully live.
