The Wolves of Savernake is the first in Edward Marston's Domesday Book series, which has, I think, not been available in e-book until quite recently. I have very fond memories of buying the early paperbacks in this series on business trips to the UK, and then pretty much reading them all on my plane flights home to the US. It now looks as if Marston may have gotten the rights back, at least to some of the early ones, and is getting them put out in e-book by Allison & Busby. (I think my old paperbacks were published by Headline ???)
Anyway,
Wolves has dropped to $1.49/£0.99 at Kindle US/UK, and it looks as if a few more early titles are out or on the way soon, at fairly reasonable prices in UK, not so much in the US.
