This being the 3rd installment of the Avery Cates series I was a bit worried about not having read any of the other Avery Cates books. “The Eternal Prison” stands on it’s own but there are references to characters and events of the past. So reading them in order may be a good idea but not necessary.
Jeff Somers creates a future world where humans are still corrupt and violent and fighting for power, and technology has advanced with scary realism. Where people get their brains digitized and uploaded into avatars and humans get augments to became part machine.
Avery Cates is a gunner (gun for hire), he’s great character that you can’t help but like and pull for, he’s a survivor. In a fight you would want him on your side (and he is usually in a fight).
Jeff Somers is an intelligent and entertaining writer that will keep you flipping pages. I will be reading the rest of the Cates series and I recommend that you do too.
The only note of caution would be language, there is a lot of foul language but the characters would be less real without it.
