Grace can do a lot of things...but can she save the planet? Or at the very least, can she help her best friend Mimi get her favorite stuffed animal back?

Lots of exciting things are happening to Grace and her friends. Most exciting of all, Mimi's older cousin Gwen is coming to stay with Mimi, and Miss Lois's class is GOING GREEN! For their "green" project, Grace and Mimi aim to inspire their friends and classmates to conserve plastic bottles. But a far more important issue is that Gwen has taken a strong liking to Mimi's favorite stuffed toy, Willoughby. Just Grace uses her empathy superpower to figure out ways to make her best friend feel better, and she makes a difference for the environment too. Yard sales, toy owls, decorated plastic water bottles, flaming onion rings, and a very entrepreneurial Sammy Stringer make this another winning entry in the JUST GRACE series.
