We work on reconstruction scenario of recently proposed dark energy model call QCD ghost with modified Horava-Lifshitz F(R) gravity. We construct the model by taking well-known power law form of scale factor. It is found that this model satisfies the realistic condition. Also, the effective equation of state parameter shows quintom-like behavior from quintessence to phantom era by crossing the vacuum era of the universe. The squared speed of sound represents the instability of the model. In this context, the cosmological planes such as and statefinder show consistency with the accelerated expansion of the universe. We also investigate the generalized second law of thermodynamics on the Hubble horizon which remains valid for all cases of scale factor parameter n.
