The NSA Files, Terry Persun, 2013, ISBN 9781482577129

This detective novel takes place in a very new and different area, inside the human soul, or spirit.

Dan Johnston is not your average private investigator. He is a shaman, which means that he can enter the spirit world very easily. While there, he can, for instance, find a missing person, or convince a cheating spouse to stop cheating. It's not fulfilling work, but it pays the bills.

The NSA learns that some members of Congress are on the receiving end of some unusual political intimidation. An important bill is coming up for a committee vote, with billions of dollars at stake. The messages are received in their dreams, delivered by their spirit totems. Dan is asked to do what he can to stop it, before the vote.

Dan's grown son, Jason (their relationship is strained), and a shaman-in-training, gets involved. What they do in the spirit world has a noticeable effect on the Internet. A couple of assassination attempts convince Dan and Jason that they are on the right track. Marian, Dan's ex-wife (and Jason's mother) is kidnapped to make sure that Dan and Jason back off, permanently.

Focus shifts to a high-tech company in Arizona. Dan is able to find the source, in the spirit world, but nicely asking Mr. Big to stop what he is doing will not work. A more permanent solution is needed (like with guns and bullets). Are Dan and Jason able to start re-building their relationship? Do they even survive?

This one is very good. It works as a regular detective story, and the look inside the siprit world is quite interesting. Yes, it is well worth reading.
