Answer 1

class Author extends Model
{
    /**
     * Get the books for the author.
     */
    public function books()
    {
        return $this->hasMany('App\Book');
    }
}

...

class Book extends Model
{
    /**
     * Get the atuhor that owns the book.
     */
    public function post()
    {
        return $this->belongsTo('App\Author');
    }
}
