It depends on the version of XeTeX and FreeFont. The shaping engine
was changed in 2013 and the old versions of FreeFont (release
2012-05-03) no longer works. You have to use the latest version from
subversion at https://savannah.gnu.org/projects/freefont/

This book was typeset with it using XeLaTeX from TeX Live 2013:
