"Good solid, if at times stolid"
Good solid, if at times stolid, look at Robert the Bruce and his reign.
Penman takes a more scholarly approach which can slow the reading aspect down a little bit, but the research seems strong and is very well presented. Bruce is a well conveyed in all his complexity and flaws, a rather rocky rise to power and then his reign and challenges that brought.
A good look at someone who not just played a role in Scotland staying a kingdom, but also well worth this effort as his actions had implications for England and subsequently the rest of Europe for generations to come. Penman does his subject proud.
