On Repentance and Repair: Making amends in an unapologetic world was a thank-you gift, not a pointed one (I assume!). The author, Danya Ruttenberg, goes carefully through the many steps of repentance & t'shuvah (returning to a healthier path) for both individuals & institutions, countries, & other groups. It's worth thinking through & I was glad to see her talk at some length about Simon Wiesenthal's important, challenging book The Sunflower. I recommend Weisenthal's book without hesitation, and Ruttenberg's with qualified enthusiasm: it may be more on the subject than most people will want to know & the book's turgid academic-but-for-the-masses prose is hard to forgive.
