NO! what are آپ talking about! the last book was he best out of all of them! it's also one of my favourite books! i love the excitment and energy she puts into the pages and it ties up all the loose ends! re-read it. now.
No, I definitely don't think she went overboard. But what made me enjoy the last book a bit less was the constant camping around and how they spent nearly half of the book trying to find the first horcrux. And the epilogue. But that's just me.
