As further details emerge about this week's shootings in Afghanistan, the situation on the ground there continues to develop. As we've heard, in recent years a lot of emphasis has been placed on the counterinsurgency effort, on winning hearts and minds as opposed to targeting terrorist cells.

In the Law of Dreams, Canadian writer Peter Behrens' first novel, an Irish immigrant, based on Behrens' grandfather, makes his way out of famine-starved Ireland to Canada. The novel came out in 2006 to wide acclaim and won Canada's Governor-General's award for fiction.
Now, Behrens has followed up with another multigenerational novel. The O'Briens opens in 1867, with teenage Joe O'Brien scratching out a living in Quebec after his father and mother have both died.
