Hi Kim,
Yes, as you pointed out very correctly there isn't any way already that makes it readily possible. Although, a little change in the code can make it work.
Step 1: Navigate to Moodle\mod\book\view.php
Step 2: Find the following line and comment it out ::
" echo $OUTPUT->heading(format_string($book->name)); "
Step 3: Save the file .
Step 4: You may now want to refresh and check your Book again !
