Epic. Dark. Realistic.
I was amazed at how true to life this story seemed. I have no personal experience in the cartel world, but what little I know seems to coincide with this narrative. If not for the voice and distinctive style of fiction, you would wonder if this was not a compilation of memoirs.
The ending was satisfying the way I hoped it would be. After a 600 page juggernaut of literary achievement, a clean, plausible, and climactic finale is expected. Few deliver as well with stakes this high.
