On this week's episode, CultureCast book editor Loretta Williams focuses on two books lighting up the Internet. 

"Ready Player One," a book by Ernest Cline and "Warcross" by Marie Lu are getting a lot of comparisons to one another. 

"Ready Player One" was adapted by Steven Spielberg into a movie that comes out in March. The sci-fi story tells of a future dystopia where the virtual world is as -- if not more -- important as the real one. 

"Warcross" is a novel with a heroine as its protagonist, that tells of yet another dystopia where virtual reality tail wags the real world dog. 

Are these novels a lot a like? Is one better than the other? 

Listen to this week's episode to find out!
