I’m not sure how well-known this series is, but I really enjoyed it. The entire series is written in first-person perspective and it has a fun dark humor to it.
Synopsis of the first book:
In the near future, the only thing growing faster than the criminal population is the Electric Church, a new religion founded by a mysterious man named Dennis Squalor. The Church preaches that life is too brief to contemplate the mysteries of the universe: eternity is required. In order to achieve this, the converted become Monks – cyborgs with human brains, enhanced robotic bodies, and virtually unlimited life spans.
Enter Avery Cates, a dangerous criminal known as the best killer-for-hire around. The authorities have a special mission in mind for Cates: assassinate Dennis Squalor. But for Cates, the assignment will be the most dangerous job he’s ever undertaken – and it may well be his last.
Personally, I think so. Each book has a definitive ending to the problem presented but then the next book will have someone the main character pissed off in a previous book coming back for revenge. So the story does follow from one book to the next but it isn’t so much an overarching story that takes 5 books to tell. I loved the ending to the 5th book which wrapped up the series though.
