So, after writing last that I hoped the series would end satisfyingly Mr. Pena confided that he thought it went downhill with the fourth book. Well, fortunately I don’t agree with him. It kept the suspense up throughout and I kept thinking “When is it going to get bad?” Well, the ending may not have had a sledgehammer impact but it was appropriate and clever in playing on the many different meanings of “sleeper.” I’ll probably go back and read the whole thing again at some point. I ended up very sympathetic to Holden Carver even though he is a man who can feel nothing. Maybe that’s where the sympathy comes from. Good work Ed and Sean. Looking forward to your future projects.
