[Plugin: Now Reading Reloaded] Single page title doesn't include name of book

I’m using Now Reading Reloaded and All In One SEO with the Suffusion theme. Everything is working except the value used for title on the page that’s displayed for a book (ex: https://brendaabell.com/?now_reading_author=martin-l-abbott-michael-t-fisher&now_reading_title=scalability-rules-50-principles-for-scaling-web-sites).

I know the problem is somewhere between the two plugins and the theme, but really having trouble tracking it down (I only know enough about WP to muddle my way through the more common stuff).

Suffusion has a special “single” template for NR that calls get_header(). So I guess my first question is whether that call to get_header() triggers anything in the NR plugin that would give me control over the document header (NR’s single.php also invokes get_header(), but I believe NR’s single.php is being overridden by Suffusion).

Just wondering if someone could give me a hint as to where I should start looking.
