How to display post title on relation field

Thanks for great plugin! I created 2 custom content types – books and authors. Now I want to display name and link to specific author under the books. I made custom relation field for that and set as output filter “Link href only”. However it displays link to specific Author but how could I change it so, that the name of the link will be taken from the Title field of Autor posts?
<?php
$hrefs = get_custom_field(‘Autor:to_link_href’,’https://yoursite.com/default/page/&#8217;);
foreach($hrefs as $h) {
printf(‘What shall i write here?
‘, $h);
}
?>

Thanks for advice:)
