This is a thorough account of Wordsworth's life written for the curious reader who does not want to know much about the poetry, although each chapter does end with a poem. It is fast-paced and holds the attention all through. My main reservation (apart from its lack of analytical material on the works) is that it digresses away from its main theme at times. Do we really need to know so much about Coleridge or Southey, for example? Some parts lose track of the main character for several pages.
Otherwise, if you just want to know what Wordsworth was like, and are prepared for some extraneous detail, this is the book to tell you.
