Lawton, John. "Central and South Asia." In Islam's Path East. Saudi Aramco World, November/December 1991, http://www.saudiaramcoworld.com/issue/199106/central.and.south.asia.htm.

This article is mostly historical tracing the golden age of Islam and the Silk Road.  It does have a few paragraphs on Central Asia, mostly discussing its historical conquerors.

The following quote, based on Lawton's experience in the region just after independence, is refreshing:
Even today, despite decades of religious repression under Communist rule as part of the Soviet Union, six newly independent Central Asian states - Azerbaijan, Kazakstan, Kirgizia, Tajikstan, Turkmenia and Uzbekistan - are still consciously and conscientiously Muslim. In fact, as photographer Francesco Venturi and I followed Islam's path east across these Muslim republics, we found the Islamic faith rapidly reviving under independent political leadership.
