I'd read The Deathly Hallows so quickly the first time, that in the decade since — whoa, kids are now reading the Harry Potter novels who weren't born yet when the books first came out — I'd forgotten great whacks of it. My memories were mainly "news articles, the cut-short wedding, lots of camping, and fighting at Hogwarts." Yeah, there's a lot more in there. I appreciated the novel's nuances more this time, I'd say. Back in July 2007, I mainly wanted to read it before getting spoiled about anything. Not an issue now.
I remember wondering, before and while reading it the first time, if the end of The Deathly Hallows would involve Harry letting himself die, specifically by going through the Veil introduced in The Order of the Phoenix. I'm the sort of entertainment consumer who, later, when the rebooted Battlestar Galactica was wrapping up, thought That sort of story, it's entirely possible that it'll end with every major character dying. Death can happen. I don't root for it, but there's plenty of it, in life and in stories. J.K. Rowling can handle death in her stories; Harry dying in a way that saved the world seemed a possible progression. Obviously I guessed wrong, but the ending as actually written also, obviously, works.
I can imagine reading the series a third time, though that wouldn't be for a while. I'll likely try reading the play Harry Potter and the Cursed Child, and some time I'll get around to the two Deathly Hallows films, which I haven't seen yet.
