Throwing it back, actually first time reading this:
I don't think I've read that since it was assigned to me in high school. I should probably go back and read it again, I'm sure I would appreciate it much more than I did at the time.
As for me, I'm almost done with this:
It's a very moving story that takes place (mostly) in NYC shortly before, during and after WWII. It's follows two Jewish cousins in Brooklyn, one of whom escaped from Nazi-occupied Prague to get there, who go on to become key players in the golden age of comic books. I knew next to nothing about that industry before digging into it and, while I can imagine that a comic book nerd would really love the premise, you don't need to know anything about it to enjoy the book, as it's really a story about family and friendship. There's also a lot of stuff about magic/escapism -- Harry Houdini shit -- so if that also interests you, then this is the book for you. But, again, those are really just plot devices that are used to tell a much bigger story, so I would still recommend it to anyone really, regardless of your interest (or lack thereof) in comics/magic.
