The award-winning author of A Dog Like Daisy returns with a moving middle grade novel from the point of view of Luna, a Labrador therapy dog who accompanies her group therapy kids when they set off on an adventure across Austin, Texas.

Luna has always wanted to be a therapy dog at Therapy Dogs Worldwide. Now she’s a whisker away from reaching her fifty-visit pin that will make it official. But when her “clients”—the children who visit her—are put into a therapy group, Luna’s routine is upended.

Like the moon, Luna shows different faces at different times. And her clients each have different needs—Beatrice is tangled in knots of anger, Caleb rushes like a waterfall, Amelia carries fear heavy like a shadow, and Hector is quiet as a rock. To comfort the kids, Luna can be what they need her to be, but can she be everything to them all at once?

When Hector doesn’t show up to a session one day, the kids set off on an unexpected quest to find him. Luna joins to keep them safe, and they must work together to almost learn the truth.
