THE REPRIEVE is episodic.
It is the second part of a trilogy. You should begin with THE AGE OF REASON, then go to THE REPRIEVE, and then read TROUBLED SLEEP.
Do not read these books if you feel elated and upbeat. The tone and mood of them are best conveyed while reading them on a dreary day.
Don't let me discourage you, because the trilogy is quite provocative, but enjoying them requires a certain frame of mind.
