Translation theory suggests choosing novels that you are familiar with or interested in. It is best to read the original text and at least one translation first, and then continue learning according to your own direction. For example, make a comparison between two different versions, or make a single version that embodies a certain translation theory.
If you write a translation practice paper, you should only choose novels that have not been published in Chinese. It is suggested to find some recently published books on Amazon's new book list or other extranets, which are generally not translated in China.
