The Rights Revolution by Michael Ignatieff
Much of the content was general or hard to disagree with as I hold many similar views. Consequently, there were few moments of unique insight or impressive sophistication, but the work was still useful as the lectures are almost what one might come up with if they had a lot of time to think about such things (but, really, who has the time?)
Lecture 3, about group and individual rights, was probably the most worthwhile to me.

Realizing it is hard to beat an encyclopedia (even a free one); here is a decent summary from Wikipedia:
In The Rights Revolution, Ignatieff identifies three aspects of Canada's approach to human rights that give the country its distinctive culture: 1) On moral issues, Canadian law is secular and liberal, approximating European standards more closely than American ones; 2) Canadian political culture is socially democratic, and Canadians take it for granted that citizens have the right to free health care and public assistance; 3) Canadians place a particular emphasis on group rights, expressed in Quebec's language laws and in treaty agreements that recognize collective aboriginal rights.
