Moscow Mansions by Barbara Guest. Viking, 1973.

The best $50 I ever spent. Maybe this is in a close tie with Own Face for my favorite poetry book of all time. There is a certain "wretchedness" of sensibility that I am constantly at war with.
This book is the antithesis of this wretchedness. Next time someone tries to foist some wretched sensibility on me, I will be armed with this book.
