Author's introduction by Lance Parkin

Because it was both a ‘last’ and a ‘first’ book, it sold very quickly. The Dying Days was out of stock before the official release date. That’s led to reports and persistent rumours that the book had a lower print run.

No, no, a thousand times no: the book completely sold out, so I know exactly what the print run was. The irony is that it’s easily my biggest-selling Who novel – it sold more than Just War, Cold Fusion, The Infinity Doctors and Father Time. And it’s ironic, because for five years, now, second hand copies of The Dying Days have changed hands for a small fortune.

They’ve sold on ebay for over fifty times the cover price. There are plenty of copies out there, but the people that have copies cling on to them. So it’s rare that one comes up for sale.
