How's the start of my novel?

For an eleven year old it is utterly brilliant, however there are a few grammatical anomalies here and there. I'm on my iPod so I can't highlight them to point them out. I would also venture that it is too short to be a complete chapter and thus far moves a little too slowly. It's well written but lacking hooks to pull your audience in. Mind you, this is only my opinion. I've been writing since your age but I've lost interest in novels and have focused on poetry for years. I would love to get back in to it, but I fear rejection you see. Well done for being braver than I am.
