William F. Nolan's Logan's Run: Last Day Vol. 1 #3

On the run, Logan and Jessica make their way into the depths of Cathedral, a ruined part of the Los Angeles Complex and first stop en route to Sanctuary. But Cathedral is also home of the Cubs, ruthless gangs of kids with only murder on their minds. With ex-partner Francis and Gant hot on their trail, Logan and Jessica's flight to freedom may end, before it even starts.
