This book was a pleasant surprise. It is a collection of essays about "apologies and reconciliation", but all the essays are to some extent tied to international relations (IR) issues. Not being an IR guy, I was worried that the book would basically only be about the effects of apologies by high-level officials on security issues and trade. Shows what I know. Also shows what I biased jerk I was (am?) when it comes to IR.
With the exception of Bindenagel's overly self-congratulatory contribution (he's a US government official, not an academic), I at least mildly enjoyed all of the pieces in the book. Some read like journalism on steroids, others like original (to me at least) interpretations of various social phenomena tied to inter-group apologies.
This book is about group apology and is about politics, so those who are interested in a broader treatment of apology (including apologies between individuals) might check out Tavuchis' Mea Culpa or Lazare's On Apology. What this book does give you is a series of essays which will provide scholars (1) ample cases studies to draw on when writing about apologies in political contexts and (2) some interesting theoretical insights that advance the discussion in a number of ways. A good book that's easy to read.
