Add Custom Post Type (Book):

// Add Custom Post Type (Book)
function shapeSpace_add_custom_post_type_book() {
	
	$labels = array(
		'name'               => _x('Books', 'post type general name', 'shapeSpace'),
		'singular_name'      => _x('Book', 'post type singular name', 'shapeSpace'),

		'not_found'          => __('No books found.', 'shapeSpace'),
		'not_found_in_trash' => __('No books found in Trash.', 'shapeSpace'),
	);
	
	$args = array(
		'labels'             => $labels,
		'taxonomies'         => array('category', 'people', 'post_tag'),

	);
	
	register_post_type('book', $args);
	
}
add_action('init', 'shapeSpace_add_custom_post_type_book');

Add Custom Taxonomy (People):

// Add Custom Taxonomy (People)
function shapeSpace_add_custom_taxonomy_people() {
	
	register_taxonomy(
		'people',
		array('post','usp_post','book'),
		array(
			'label' => __('People'),
			'rewrite' => array('slug' => 'person'),
		)
	);
	
}
add_action('init', 'shapeSpace_add_custom_taxonomy_people');

Add Custom Taxonomy (Animals):

// Add Custom Taxonomy (Animals)
function shapeSpace_add_custom_taxonomy_animals() {
	
	register_taxonomy(
		'animals',
		array('post','usp_post','book'),
		array(
			'label' => __('Animals'),
			'rewrite' => array('slug' => 'animal'),
		)
	);
	
}
add_action('init', 'shapeSpace_add_custom_taxonomy_animals');

Modify main WP query:

// Modify Main Query
function shapeSpace_modify_query($query) {
	
	if ($query->is_main_query() && is_home()) {
		
		$meta_query = array(
			array(
				'key'     => 'my-mood',
				'value'   => 'happy',
				'compare' => 'not like'
			)
		);
		
		$query->set('meta_query', $meta_query);
		$query->set('posts_per_page', '3');
		
	}
	
}
add_action('pre_get_posts', 'shapeSpace_modify_query');
