Two new books, as well as one from the recent past, join the list this second weekend in April.

The oldie being Post associate editor Bob Woodward’s 2010 book on the Obama White House and the twin wars in Iraq and Afghanistan. Not quite sure why it’s back, though it’s gratifying to know that people are still concerned about the wars and their staggering cost, both human and emotional.

Garrett Graff, the editor of the Washingtonian magazine, finds his new book debut on the list this week, a behind-the-scenes look at the FBI and a cadre of agents determined to protect the nation (and its values) in a rapidly changing security environment. It’s surprising it didn’t also land in the general nonfiction top 10, but I expect it will in the next few weeks.

A bit of international relations (and searing humanitarian drama) hits the list with journalist Peter Godwin’s chronicle of his journey to Zimbabwe (his childhood home) amid the tense 2008 presidential election that offered a glimmer of hope that Mugabe’s long, tyrannical reign might at last be drawing to a close. Instead, Godwin found himself covering the violence and horror that erupted when Mugabe refused to concede power.
