h1 in template file for taxonomies

Say that I am creating a site with a custom post type of books. I then create a taxonomy of genre. I then post a book with the genre of science fiction.

How would it be possible to display "genre: science fiction " in the <h1> ?

I have created a template file for the taxonomy and it works fine. The only problem is that header is now "blog archive" or what ever write it to be.

what code do I need to properly display what I am asking for?

Thanks.
