In I'm An Alien and I Want to Go Home Jo Franklin does a much better job with both humor and humor that's integrated into story. This is one of those child outsider stories, in this case taken to an extreme. And, yet, for an "alien" story, it is very grounded in reality. The resolution here is one that makes sense and is reached in a logical way.
The book has many illustrations by Marty Kelley. With both subject matter, humor, and packaging, this could be a fun read for younger children.
I saw Marty Kelly at a NESCBWI event a number of years ago, about, I believe, author appearances at schools. He does a lot of those.
Interesting factoid. Kelley is an American writer located here in New England. Franklin is British. I had a British cover artist for the hardcover edition of one of my books, so I shouldn't be all "They're from different countries!" about that situation. Nonetheless, I am.
Children's publishing is probably a small world.
