python requests and bs4 how to navigate through the children of an element

Question

so this is my code

from bs4 import BeautifulSoup
import requests
import time

URL = 'http://www.vn-meido.com/k1/index.php?board=17.0'

# loads page
r = requests.get(URL)
soup = BeautifulSoup(r.content, "html.parser")

# gets the newest book
book = soup.select_one('td[class^="subject windowbg2"]').text

while True:
    # reloads the page
    r = requests.get(URL)
    soup = BeautifulSoup(r.content, "html.parser")
    # gets the newest book
    new_book = soup.select_one('td[class^="subject windowbg2"]').text
    # checks if a new book has been uploaded
    if book == new_book:
        print("no new book found")
    elif book != new_book:
        print(new_book)
        book = soup.select_one('td[class^="subject windowbg2"]').text
    # repeats after 30 seconds
    time.sleep(30)

but if you go to the website and have a look I get the text of the newest book uploaded but I want to be able to separate the title and the author and the title and author are in different elements but they don't have a way to identify them (like a class or an ID) so if you can help please do, thanks
