Helen Vendler, widely regarded as our most accomplished interpreter of poetry, here serves as an incomparable guide to some of the best-loved poems in the English language. In detailed commentaries on Shakespeare's 154 sonnets, Vendler reveals previously unperceived imaginative and stylistic features of the poems, pointing out not only new levels of import in particular lines, but also the ways in which the four parts of each sonnet work together to enact emotion and create dynamic effect.
