Well, I've been over the Proof copy of Lifelights the requisite three times (Not me exactly... I roped in some friends) and I think we've picked up everything that needed fixing.
Truth be told, one of my friends had a confession when she returned her copy of Lifelights yesterday. Apparently, she started off okay, taking notes on anything she thoughts might need attention (and then it turned out they didn't!) but after a while, she got so 'into' the story that she completely forgot what she should be doing, got her husband to do the ironing for her and finished the book in record time!! Not exactly what I'd asked for... but who could get cross about THAT?
Next step... send the improved version off, wait for the 'new' proof to come back and if that's all looking good, then hit the 'publish' button!
