I ran across a trailer for this book a few weeks ago and... wow. I immediately checked out a copy from the library and found the book even more beautiful and powerful than revealed by the trailer. As the grandchild of immigrants, the topic, for me, is poignant, and in light of the current political situation in the US, this book offers inspiration and hope.
In addition to the trailer, author Dave Eggers posted a letter to his readers on Amazon. You can find the letter here (just scroll down a bit and you'll find it).
