I am now reading the newly published biography of Van Gogh by Steven Naifeh and Gregory White Smith. What a great work and what a tremendous undertaking this must have been! It is early days yet to judge about the entire book (I am on page 81, so still 988 pages to go..!), but what I have read so far is really high quality, not only in content but also in style.
