Unlike the first three of this series, each of which is more than it seems at first, I knew Black John would be tough. The author includes some warnings about subjects, or a note, really. She didn't mention serious self-loathing, perhaps because by this point the reader strongly suspects that already. But how John reached this point? Oh boy. And about that: I appreciated the way Lane constructed this story, with memories laced through current events rather than breaking action for a separate flashback. The way those memories and the current terror/interest are woven together works beautifully. And when John re-integrating with his friends back in Sacramento, Lane ties the four stories together and it is beautiful. And then, the end.
Chase, Dex, Ethan, and John. These are great stories, and now I have to wait for the next one, darn it.
