Oh bum! I wasn't very clear there, was I? As far as I know, tdu000, 'Fire Star' was the last in that series. I had to wait for it to come out in paperback (£6!!) b/c I refuse to pay for hardback!

I can recommend another series that's highly imaginative, though. Written by Elizabeth Kay, the first is called 'The Divide', followed by 'Back to the Divide' and we've just started 'Jinx on the Divide'.
