Seven-year-old Zinni loves learning about the world - especially the ocean and the wondrous creatures that live there!

Of all the world's fascinating sea creatures, her favorites are mollusks, like squids and sea snails. When Zinni's mommy, a rabbi, tells her the story of a mysterious ancient mollusk whose vivid blue ink is sacred to the Jewish people, Zinni is determined to find it . . . even if the only place she can search is in her dreams.
