I thought it was a great book. I thought it was a shame that it was not allowed to be two books as it was initially envisioned. The next of Lonemagpie's books is on auto-buy for me.
I sincerely hope there will be one! Though with all 2012's books locked in, I guess nothing of that sort will happen till at least 2013...
(Which may be just as well, as I've two *very* time-intensive nonfiction books due for delivery on June 30th next year, the Blakes 7 one and another one.)
