Query: Does emergent scenario in Ho\v{r}ava-Lifshitz Gravity demand a ghost
  field?   The non-singular model of the Universe i.e. emergent scenario is now very
well known in cosmology. In Einstein gravity such type of singularity free
solution is possible in the context of non-equilibrium thermodynamical
prescription (both in first and 2nd order theory) with particle creation
mechanism. Also there are various models of emergent scenario in different
gravity theories. The present work is a twofold attempt namely (i) it has been
examined whether it is possible to have singularity free solution in
Ho\v{r}ava-Lifshitz modified gravity theory, (ii) if such singularity free
solution exists then whether such solution is thermodynamically viable. It is
found that perfect fluid matter distribution with phantom nature can generate
such type of solution for closed and flat model. Finally thermodynamical
analysis has been studied both at the apparent horizon and at any arbitrary
horizon.
