We regret the need to cancel next week’s book event for Diane Ravitch, but the author has cut short her promotional tour for The Demise and Reincarnation of the Not-So-Great American School System to finish up her next new book, provisionally titled Vouching for Vouchers II: How School Choice and Accountability Will Save America’s Schools After All. She explains: “I was going through my attic this spring, trying to find my collection of Winslow Homer reproductions. But I came across some more of my old writings, and started reading…” Disappointed attendees, however, will receive complimentary copies of her earlier work, Vouching for Vouchers I.
