Just to clear some things up as the current Amazon listing for DQ2 is very confusing (if you've ordered through them - or intending to), they list the following:
Hardcover 15 Nov
The £8.99 paperback is the small 'mass trade' paperback that is not out until next year 2013. Don't really understand why Amazon lists this so early, but hey ho.
Right, the two hardcovers - again, this is confusing. One is the hardback and one is the large trade paperback (the big sexy version of the paperback), both out on 15 Nov this year. I'm not clear myself which is which, as both have been cleverly listed as 'hardcover' - and I have asked my publisher to notify Amazon to get this changed. I am assuming the more expensive version is the actual hardback, but that may not be the case. I'll chase them today and see if I can get clarification.
At the moment, I haven't heard anything about promotional items for The Heart of Fire. I'd like to think there might be some (have plenty of ideas!). I'll keep people posted. Don't worry, if there are any pre-order promotions, then just keep a copy of your pre-order email and hopefully you won't miss out.
