No Escape! — Francine Pascal

Trouble underground...

Identical twins Elizabeth and Jessica Wakefield are about to say good-bye to sixth grade--forever! But it's not over yet....

The entire sixth grade is going cave exploring--spelunking! At first, Elizabeth is thrilled to roam through the Ice Cave with her friends. The cave is beautiful--it shimmers with every beam of their flashlights, and Elizabeth even discovers and underground waterfall!

But when the guide breaks his leg, it looks like the sixth graders are in for a bigger adventure that they counted on. Will they find their way out of the twisted underground maze? And can they do it in time to save their injured guide?
