Reviving a Bonsai

I bought a Bonsai as a gift and it has been sitting outside for a year and a half. Winter, summer and winter to current.

It was never looked after. Never watered. Left in the shade. It has no leaves left. I was thinking of putting this in my grow area and watering it. Will this bring it back? Any other ideas / tips?

I tried Google and will continue searching but sometimes asking is faster.
