Soma by Charlee Jacob

From the crumbling ruins of a Cambodian jungle temple to the arid canyons of west Texas, exotic demons of the ancient past collide with more modern devils. As crippled residents in a small Cambodian village try to rebuild their lives in a shattered country, their god returns to them, providing hope and a dream of survival. But their god has returned as a former American GI, and their hope for peace is a drug that opens the door to untold horrors. Their beautiful nirvana waits only at the end of a road traveled by nightmares. It is a world peopled by the bizarre and the unearthly, in which damnation and redemption can come in the most terrifying forms.
