Shortcode to display latest post from one category

[jodzeee]

I'm trying to display the most recent post from one category on a page. I thought I'd try to do it without a plugin and I'm close ... but where do I define which category?

add_shortcode('recent-posts', 'my_recent_posts_shortcode'); */

function recent_posts_function() {
   query_posts(array('orderby' => 'date', 'order' => 'DESC' , 'showposts' => 1));
   if (have_posts()) :
      while (have_posts()) : the_post();
         $return_string = '<div class="current-offer">'.get_the_content().'</div>';
      endwhile;
   endif;
   wp_reset_query();
   return $return_string;
}

function register_shortcodes(){
   add_shortcode('recent-posts', 'recent_posts_function');
}

add_action( 'init', 'register_shortcodes');
