Up the creek . . .
Volume 5 in the Chance "Cash" Register blue-collar series.

He walked away from the shipping clerk job at the smut warehouse to rescue what remained of his sanity. Only now he's up sh*tz creek. There is zero money coming in for grub and other necessities. What makes it worse: No one wants to hire him. It goes on for months, forcing Register to use plastic to get by. Even so, he knows, the thing to do is to endure long enough to see a break and for his luck to change.
