I spent a lot of time on the road at the end of last year and read three surf related books in just over a week.
1. Elko - I would give this 10/10
2. NC and TC - I would give this 9/10
3. Bob McT - first book. Would give it a 5/10 maybe a 6. No disrespect but after the other 2 it was dull in comparison. A good read but nothing on the others - sorry Mac

If you are after a few other general interest books I would suggest
Outliers - Malcom Caldwell - great book with some interesting thoughts
Keith Richards biography - long but very enjoyable
Boomerang - Michael Lewis - one of my fav authors (you may recall Moneyball) - a good run down of what was happening across the world just a few short yrs ago
Pale Blue Dot - Carl Sagan. Great read.
Antifragile: Things That Gain from Disorder - Taleb. A story of things that need chaos to survive and thrive.
The 4-Hour Workweek - Tim Ferris. Everyone should read this one - lots of very useful ideas in it.
Why Evolution is True - Jerry Coyne. Lines up the evidence from genetics, paleontology, geology, molecular biology, and anatomy on why we have evolved - stopping the intelligent design argument in its tracks!!
If you want more let me know.
