Ben Hatke’s Zita the Space Girl: Far From Home is a great science fictional kids comic. Zita and Joseph find a big red button in a field. Zita presses it and Joseph gets sucked through a vortex. Then she summons up her courage and presses it again to go after him. They’ve both ended up on an asteroid filled with aliens (and robots), some of whom speak English. The asteroid is going to be destroyed by a comet in three days though, so they need to get out of there. Joseph has been kidnapped and taken to a castle to be imprisoned and Zita gathers up her resources to go find and rescue him. She makes allies and gets betrayed and eventually everything works out pretty well.
There’s nothing crazy complex going on with the plot, but the characterization is fun. There’s a war-bot that likes to tell stories of his escapades (much like warship in The Culture novels) and a giant mouse who doesn’t speak but prints out little messages from his collar. The art is cute and the story moves really quickly. I liked it a lot.
