If you can stomach the subject, Red or Dead by David Peace is excellent. Not an easy read, 250,000 words and 700 pages, lots of methodical repetition as Peace tries to convey the almost autistic focus Shankly has on whatever he's doing at the time. Not sure how much of it is dramatic license but Shankly comes of as a decent man who is lost without his team.
Liverpool Football Club come off as a classless organisation who use people until they don't need them any more (I never knew their club secretary hanged himself under the kop in the 60s, a victim of burnout) then throw them away. Drunk Hughes "Everton are tragic" chant makes Bill cry and turn his back on them for a period.
