Hello!<br/>I was wondering which article would be the most appropriate in this case.<br/><br/>The author of <b>a</b> well-known book "Martin Eden"....<br/>OR<br/>The author of <b>the</b> well-known book "Martin Eden"...<br/><br/>It feels that the first is right, however, the one with <b>the </b>seems reasonable for the fact that we talk about some specific book.
