  Deviation of the gamma-ray energy spectra of Flat Spectrum Radio Quasars
(FSRQs) from a simple power law has been previously observed but the cause of
this remains unidentified. If the gamma-ray emission region is close to the
central black hole then absorption of gamma-rays with photons from the broad
line region is predicted to produce two spectral breaks in the gamma-ray
spectra at fixed energies. We examine 9 bright FSRQs for evidence of breaks and
curvature. Although we confirm deviation from a simple power law, break
energies are usually not where predicted by the double-absorber model. In some
objects a log-parabola fit is better than a broken power law. By splitting the
data into two equal time epochs we find that the spectral shape of many objects
varies over time.
