Thanks for your recommendation, too. I've just read an NYT review of it [1] and am definitely going to read it. From the review:

Gopal’s book is essential reading for anyone concerned about how America got Afghanistan so wrong. It is a devastating, well-honed prosecution detailing how our government bungled the initial salvo in the so-called war on terror, ignored attempts by top Taliban leaders to surrender, trusted the wrong people and backed a feckless and corrupt Afghan regime. The book has its flaws, minimizing the role of neighboring Pakistan in the Taliban’s resurgence and letting the Taliban off too easy. But it is ultimately the most compelling account I’ve read of how Afghans themselves see the war.
