InterWorld

Maybe because InterWorld wasn't written by Gaiman alone, but in a collaboration with Michael Reaves, I can't help feeling it would've been better executed as the animated something they wanted at first. This doesn't read like a Neil Gaiman novel. It's very YA-ish (middle grade, even?), and I can picture my younger self enjoying it very much, but I've read my fair share of Gaiman stuff over the years, and I felt let down by this one.

It is what it is: your average teen fantasy/sci-fi adventure story.

I've only read one other “kid's” book by Neil Gaiman and that was “The Graveyard Book.” I always thought that the only reason that book was classified as for children was because it had a child protagonist. The story was deep and could be enjoyed by adults. Interworld, on the other hand, was not. Not a bad book, just clearly meant for children and reminiscent of the Animorphs and Goosebumps books I would read as a kid. Don't expect any nuance.
