William Wordsworth's iconic relationship with his 'beloved Sister' spanned nearly fifty years. Separated after the death of their mother when Dorothy was six, and reunited as orphans after the death of their father, they became inseparable companions. This is the first literary biography to give each sibling the same level of detailed attention; with Dorothy's writings set fully alongside her brother's, we see her to be the poet's equal in a literary partnership of outstanding importance. But Newlyn shows that writing was just one element of their lifelong work to re-build their family and re-claim their communal identity; walking, talking, remembering, and grieving were just as important. This rich and holistic account celebrates the importance of mental and spiritual health, human relationships, and the environment.
