Yes, it can be done in this way :

authors=Author.objects.prefetch_related('book_set')

If you want to filter by an attribute(name) present in Author model you can simply filter it by writing:

authors.filter(book__created__gt='your_date')

This will filter all the books that have create date(created attribute in the Book module) greater than your date.
