Absolutely! It ties up all the loose ends and brings the plots and sub-plots to conclusions. It is very satisfying to see JK Rowling bring such a complex series to frution. You might dislike some of the specific outcomes, but that is the nature of a great tale.
If you've read the first six, then you're cheating yourself not to read the seventh. It's the last in the series and it answers all the questions posed in the first six. It's an exciting read that shouldn't disappoint.
The seventh book of the Harry Potter series if the final one. It sold 15 million copies during
the first 24 hours after its release and broke all sales records of fastest selling book ever! This book received several awards and was listed as one of the best books for young adults by the Library Association.
