Do you remember when you read Harry Potter and the Order of The Phoenix? That moment when you read the words:
But Sirius did not reappear (p711)
Did you cry? I did. And I waited. I kept thinking, no, this can’t be right. Sirius will find a way to cheat death, surely!
I waited some more, all through The Half-Blood Prince and right up to the bitter end (Harry and Ginny? Really?) of The Deathly Hallows, hope sprang. Until it withered and died.
How cruel was that? Poor Harry lost his parents, then finally found some family with Sirius and Dumbledore only to lose them both! Oops, spoiler alert, Dumbledore dies too. With all the magic and prophecy floating around, surely she could have found a way to save one of them?
