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. . . .
