Got it at a signing and talk session last Thursday. Well worth the £25 (including an hour talk by RM in Ely Cathedral) IMHO. I also waited for the crowd to disperse (an hour signing session as it happens) and had a quite nice chat with him about disabled bushcraft. Very honest and upset loads as he says it as he believes it.
It is set in the Boreal Forest (didn't know there were so many different Sammi groups with different lifestyles) and is back to basic stuff like knife grips, firesticks, firelays, etc. It has loads of pics taken by RM over his travels and I love it as it brings together loads of important info that is scattered in other books
