Query: Great end to a trilogy!

I loved POI. Then I had a hard time with the brutality of DWB, but was glad I finished it. Black Light was the best of the three to me. It seamed the books together smoothly. Having Russ as a "protagonist in training" was fun. Like Russ, we could all learn the lessons of BL Swagger. Confident, realist, focused, morally anchored, and forgiving to a large degree in the faults of others.Make sure to read the trilogy, in order, and prepare to become a Swagger groupie! I just loved the ride through these books.
