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 \sim 0.02 \div 0.2 and non-Gaussianity of equilateral type with f _ { NL } in the range from -50 to -5 .
