Category parameters work only for default WordPress posts. With custom post types you must use tax_query.

new WP_Query( array(
    'post_type' => 'book',
    'tax_query' => array(
        array (
            'taxonomy' => 'your_custom_taxonomy_slug_here',
            'field' => 'slug',
            'terms' => 'english',
        )
    ),
) );
