A while back, I found this Berkeley Breathed book at Auntie's.
Disney is making a movie version of the book now, which if you know Berkeley and Disney, is incredible.
You can find a bit more of the story here (along with more history between Berkeley and Disney), but basically it's this:
Milo (the son) doesn't much care for the way his mom treats him (making him do chores and eat his vegetables), but when Martians kidnap her, well he has to do something, right? So he stows away on the alien ship to try and rescue her.
Now, for those of you in the bookstore with me at the time, you might remember my reaction to the book's ending. But if you really don't want it spoiled, I'll hide it. Show/Hide
...although it's not much of a spoiler, considering how much of it is on THE COVER!
Milo (on Mars) trips and falls and breaks the helmet of his spacesuit. The air escapes and he passes out, right as his mom finds him. Seriously, it's ALL ON THE COVER. Anyway, next page is double-spoilered. Show/Hide
Milo wakes up to find he is wearing an unbroken helmet.
Yeah. His mom took off her own helmet to save him. Milo finally understands the depth of his mother's love for him.
Overall, a pretty good book, if a bit abrupt at that one point. I'm curious how they plan to stretch this tiny story over a full-length movie though.
Semi-relatedly, here's an article Berkeley wrote about modern movies.
