Re: Holy ....! Doctor Who/Star Trek Crossover coming From IDW!
Amazon already has the omnibus available for pre-order with release scheduled for October:
Presumably the UK version will be available at some point after this, though I imagine you should be able to order it if you're willing to pay the extra postage or Book Depository carries it. I thought the IDW monthlies were distributed in the UK - I get the impression from the discussion here that they are not (I know the early Doctor Who series with the Tenth Doctor wasn't but I thought that changed). I imagine Panini probably has something to do with it if they have a monopoly with DWM and Doctor Who Adventures (which we do not get over here and no one's bothered to do reprints of the comic strip for us).
