Zee has had it. She had Mara all to herself...until a new puppy named Kiskah showed up. Now everything is all about Kiskah, and Zee has had enough of that, too. In an angry moment, she concocts an ill-conceived plan to sneak outside and go missing just long enough to make Mara regret neglecting her. Besides, it's a fascinating world out there, a place she's wanted to explore for a long time. Zee's "I'll show you" plan backfires when she chases a butterfly far from the safe confines of the backyard. Lost and alone, it is then that her adventure in discovering the Golden Rule begins.
