  We find a general model of {\em single-field} inflation within the context of
type IIB string theory compactified on large volume Calabi-Yau orientifolds
with $h^{2,1} > h^{1,1} = 2$. The inflaton is the axion part of the
complexified K\"{a}hler moduli and the resulting scalar power spectrum is red,
and can easily be made compatible with WMAP3 bounds on $n_s$. This model
overcomes the $\eta$-problem using gaugino condensates on wrapped D7-brane
while keeping the tuning of the parameters minimal.
