Can you recommend any critically acclaimed top fiction books from 2012?

Well, 'The Left Hand of Darkness' by Ursula K. Le Guin is a must - mention. It's known for its exploration of gender and society in a science - fiction context on the planet Gethen. 'Ringworld' by Larry Niven is also among the best. It presents a gigantic artificial ring in space and the adventures and challenges faced by the characters exploring it. 'Flowers for Algernon' by Daniel Keyes has science - fiction elements in its story of a man whose intelligence is artificially enhanced and then deteriorates, and it has been praised for its emotional depth.

The aforementioned 'The Road' by Cormac McCarthy. Critics lauded it for its bleak yet beautiful portrayal of a post - apocalyptic world. The way McCarthy subtly weaves in the threat of cannibalism as part of the horror of this world is masterful. It's not just about the shock value of the topic but also about the human condition in extreme circumstances.

Among them, 'The Corrections' was highly acclaimed. It received numerous awards and nominations for its incisive look at family relationships and the state of modern America. Critics praised Franzen's writing style and his ability to create complex, believable characters.

As of now, there are no critically acclaimed Invader Zim adult fictions that are widely known. The series is mostly recognized for its original, more family - friendly content. The nature of 'Invader Zim' doesn't really lend itself easily to adult - only critical acclaim as it's a very stylized and often comical show aimed at a broader audience.

One could also consider 'Atonement' by Ian McEwan. Set in different historical periods, it has a complex love story at its core. It's a beautifully written novel that examines themes of guilt, love, and the impact of false accusations. While it has elements of passion and love between the characters, it's not about sex in an improper or overly emphasized way but rather part of the exploration of the characters' emotions within the historical backdrop.

Another example could be 'Ready Player One' which has a lot of fan - like adoration for various pop - culture references. While not strictly a traditional fanfiction - based book, it shares that sense of building on existing cultural works and fandoms. The book was well - received critically for its unique take on a future world filled with references to classic video games, movies, and more. It's like a love letter to all those different forms of media, and in a way, similar to how fanfiction builds on existing stories.

Some of the best critically acclaimed science fiction books include 'Dune' by Frank Herbert. It has a complex and immersive world-building with its desert planet Arrakis and the politics and power struggles around the spice melange. Another one is '1984' by George Orwell, which, while often considered a dystopian novel, also has strong science - fiction elements in its vision of a totalitarian future. And 'Brave New World' by Aldous Huxley, which explores a future society based on genetic engineering and social conditioning.

J.M. Coetzee's 'Age of Iron' is also highly regarded. It's a complex novel set in South Africa during the apartheid era. Coetzee's exploration of moral and political issues in the story is masterful.

Henry Miller's 'Tropic of Cancer' is another one. It contains a lot of sexual and bawdy descriptions. It was initially banned in the United States but later was seen as an important work in terms of its experimental style and its look at the expatriate life in Paris. But again, it's not for everyone because of its raunchy nature.
