There have been several comments in the guestbook about availability of The Temporal Void in the UK. There are two separate issues at play here:

Regarding the Waterstones limited edition: There was a problem at the printers with the box they come in, and it all had to be redone. They will be in the stores by 24th Oct.

In addition, Borders has got a new distribution centre, and are having trouble with all new books. They hope to be back on track soon.
