Good premise, but the book's mostly not about that. Minimal development of the issues of the last supper, death penalty, contemplating life.
It's mostly a gangster/revenge story that's more tell than show. The main character spends a lot of time explaining why he likes cooking and also how hard he's had it and why the villain is bad. Even the ending, which is supposed to be uplifting (I think?) has him reading the most negative spin on the people he's watching. The whole book is a lot of downers, and there's really no one to root for.
Plot hole problems: I'm pretty sure that's not how TV shows work, switching producers and "going national." How did he get access to Cole's car and jacket? Why would a guy as paranoid and good at outsmarting everyone not notice a GPS tracker on his car? How does he have so many connections to other smugglers/dealers that far afield of Austin? And there was a dead guy in his fridge and he was just like "Well, if I bleach everything, it's still OK to serve food out of here."
