  We present a setup that provides a partial UV-completion of the ghost
inflation model up to a scale which can be almost as high as the Planck mass.
This is achieved by coupling the inflaton to the Lorentz-violating sector
described by the Einstein-aether theory or its khronometric version. Compared
to previous works on ghost inflation our setup allows to go beyond the study of
small perturbations and include the background dynamics in a unified framework.
In the specific regime when the expansion of the Universe is dominated by the
kinetic energy of the inflaton we find that the model predicts rather high
tensor-to-scalar ratio r ~ 0.02 $\div$ 0.2 and non-Gaussianity of equilateral
type with f_NL in the range from -50 to -5.
