That was quite an introductory chapter and it starts a number of interesting threads. It's prety likely that Harry wasn't killed, "only" rather injured (nothing wizarding medicine can't fix fairly promptly, but still...) and it's clear that Ginny is not going to play Penelope to Harry's Odessyus. Too, it will be interesting to see if that Obliviate worked like it was supposed to.
All in all, this is an excellent first chapter that clearly draws the reader into the story and I'm quite looking forward to more.
Author's response
Sorry to have to tell you this but Harry's taking a dirt nap. It's rather tough to bounce back from being gutshot with a shotgun and wrapped up in dropclothes.
