Covered from head to toe with one-of-a-kind tattoos, Marigold is the brightest, most beautiful mother in the world. At least, that’s what Dolphin thinks—she just wishes Marigold wouldn’t stay out quite so late or have mood spells every now and again. Dolphin’s older sister, Star, loves Marigold too, but she’s tired of looking after her. So when Star’s dad shows up out of the blue and offers to let the girls stay with him, Star jumps at the opportunity. But Dolphin can’t bear to leave Marigold alone. Now it’s just the two of them, and Dolphin is about to be in over her head. . . .
