The Sci-Fi family tree is a rather curious one, and it includes inbreeding, infidelity, and other Jerry Springeresque connections. For example, someone at Sony Reader Store listed the fantasy novel Game of Thrones as being the child of Total Recall and A Wrinkle in Time. Who do you think was being cheated on, I wonder? And then in the next generation The Hunger Games has an incestuous relationship with its cousin Game of Thrones to produce The Fault in Our Stars.
I do not mean to cast aspersions on a person's family history, but whoever designed this family tree has serious issues. I was under the impression that family trees were supposed to fork, not merge. (No hillbilly jokes, please.)
Over the past year Sony has been making a serious investment in their ebookstore. They have released a new reading app that supports Epub3, added expert reviews, and started working on new ways to market ebooks to readers. It's pretty clear that their primary goal is less to make money on ebooks and more to cash in on the content sold on their hardware, but they are still a presence in the market.
