Newt wakes up in an alternate reality as he slowly becomes someone else. He must avoid his counterpart who also lives in this realm (Jack Frost). If the two boys touch they will both die, but if Newt and his fellow gladers do not return to their reality they will become their characters and forget who they are.
Rated T for some blood and mature themes
This is from Newt's pov but switches to some of the other glader's pov's and their counterparts. Chuck and Teresa are alive in this.
