Loosely arranged around a birthday celebration, this meandering tale never finds its focus. Lizzie is stranded on a deserted island with nothing but her ""ever-busy scientist"" parents and a giant computer. In her frustration and loneliness, she and her pal Starfish decide to run away. Seâ€žor Mundo (a personified cartoon of Earth) offers them a place to go--the entire world. Other planets vie for her attention, slinging insults at each other until Lizzie chooses Mars for its red color. Hurled through space, she finds Mars to be inhospitable and has to be rescued by Seâ€žor Mundo. Following side trips under the sea and into the jungle, Lizzie returns for a no-place-like-home birthday bash. Whiny Lizzie is impossible to like; Mariscal's cartoons have the energetic lines of comic-book art, and provide a fun grand finale. The book never achieves magic, but offers some satisfying glimpses of real adventure.
