This is a great book about a friendship between two girls. I think their antics reminded me of playing with my own friends at the time. Marissa and Laura pretend spies are following them, put on a rock show for their moms, dance ballet, play pirates, and protect each other from robots. Sometimes they get mad at each other, but quickly make up after having some cool-off time alone.
Unfortunately, I couldn't find much information about the author. It appears she wrote a few books around this time period and hasn't had anything published since. It's too bad because her words and illustrations are so fun.
