By the way, my agent responded last week - she's delighted with the revisions so now the book goes out to publishers.
I've now taken up the delicate hopeful-writer stance (and you thought Pilates was difficult - try this): feet on the ground while head in the clouds and heart racing - just a little bit. It's a posture I've been perfecting for some years now. Does wonders for the abdominals but is perhaps a bit detrimental to the blood pressure. It's been a while since I've stretched my head quite this high - but hey, it's like riding a bike: it all comes back to you.
Now it's a waiting game. Again.
