BJJ Book (Kindle), PFL is Pushing it!
My friend, BJJ instructor Mark Johnson has his second book out on Kindle. I've been reading his blog for years and he's a good writer and thinker.
"Borrowing the Master's Bicycle has jumped from #30 to #19 on Amazon's Kindle list (under BJJ) in one day! If you bought one, thank you. Still looking for the #1 spot." - Mark Johnson on fb.
