I just finished this book called Carry On, and it was so incredibly good + it was written by favorite author, Rainbow Rowell. It?s probably now my favorite book of all time I might say. It?s a bit of a knock off of Harry Potter, except it?s a gay romance and has a widely different plot; it?s mainly just the setting that?s pretty similar, but it doesn?t get to the point where it?s overwhelming similar.
Sounds like it's worth checking out. I finished Prisoner of Azkaban this evening and had been thinking about if it were possible to write a story with some similarities to the HP books without them being perceived a copy.
