What is the response of the Lubavitcher rabbinate (as in Lubavitcher rabbis in general, I am not referring to any specific rabbinical body) to the new book on the Rebbe zt"l by Josef Telushkin? Is it perceived to accurately portray the history of the Rebbe's life? Are there any book reviews available online written by prominent Lubavitcher Chasidim?
chabad.org Lubavitch's primary online voice carries a fine review of the book: http://www.chabad.org/news/article_cdo/aid/2619597/jewish/Biography-of-the-Rebbe-Hits-New-York-Times-Best-Seller-List.htm
It would seem they strongly approve.
