No time to say goodbye

"This will not be the last time you know from me"
That was the last thing I heard before waking up in a place where the residents are sent to hell for a break.
Desmond Reihl, a former prisioner, tries finding his way home, and ends up finding ways unknown to all.
Plot twists everywhere is the only thing for granted.
This gun' be good.
