Its interesting, from a marketing perspective, that it seems to be being sold as the story of a Hull FC player gone astray, with little focus on the potential Rovers audience. From the choice of title, picture, co-author and the blurb, it looks much more like one for you than for us.
Tbf, he spent the large majority of his career with Hull, and you are a bigger market, so it does make sense. On the other hand, I guess there's still a few black and whites who might be curious, but won't want to be lining his pockets, on principle - see above.
i dare say I'll pick up a copy and have flick through, all the same, but the eagerness of my anticipation has diminished over the years. From a selfish POV, it is 5 or 6 years late. While time can give better perspective, the Rovers-centric bits won't be as compelling as they might have been back then.
