There are illos throughout the book and I really enjoyed looking for Thompson's cartouche.
Okay, more about the book. It's YA, has big letters and tons of space between the lines to stretch it out. It isn't even a real book because it doesn't end, you'll have to read the next book to find out more. There's a lot of uninteresting additional matter that if you pulled it would let you bring this "book" down to the size of a part of a book and get all of them in one.
The characters are vague and implausible. The IDs between the warring parts (alternate WWI) are Clankers -- machines, and Darwinists -- biogenics. The thing is, biogenics is making new things while the machines are just like, well, machines.
We had one person in the group who really liked the writing -- he said it was "lucid." The rest of us generally disliked at least one thing and then agreed with things of others.
