FROM SARAH:

When three sibling bears break mama's beautiful blue seashell, there's only one thing to do: go on an adventure to find her a new one. This is one of my new favorites, but it can be hard to come by, even though it's not very old. Alas! See if your library has it.

FROM THE PUBLISHER:

Three bear siblings break their mother’s favorite blue seashell, and rather than tell her, they decide to set out in their sailboat to find her a new one. On their quest they encounter salty sailors, strange new islands, huge whales, and vast seas but no blue seashells. When a treacherous storm suddenly blows in, the three bears find themselves tossed about in their little boat, far from Mama. What will become of their search, and what will it take to bring them safely home?
