You could use get_posts() to get posts of a particular type, then use a for loop to print out links, titles, etc as required.
Maybe put this in a custom template for your “All book pages” page. More info on templates here.
Example:
$posts = get_posts(array(
"post_type"=>"book_pages",
"post_status"=>"publish",
"posts_per_page"=>-1
));
if ($posts && count($posts)>0)
{
global $post;
foreach ($posts as $post)
{
setup_postdata($post);
the_title(); //prints out the title of this post
}
wp_reset_postdata();
}
