School’s out…and of course that means it’s time for fun! Grace and her friends are always ready for a little adventure, and Grace’s backyard is the perfect place to set up headquarters.

The group’s exploits, both real and imagined, provide all kinds of unexpected rewards---and might even land Grace on an actual stage in a real theater production!
