Rebecca Able is having a most memorable Passover. She is sailing the Caribbean with her grandparents aboard their sailboat, the Diaspora. Rebecca learns first-hand what the Exodus from Egypt must have been like for the Jewish people--at once dangerous and frightening, liberating and wondrous. And a cross-cultural friendship she makes in the Bahamas helps Rebecca recognize and appreciate the opportunities she has in her own life. On this unforgettable trip, Rebecca learns not only how a Passover seder is celebrated on board a sailboat; she also learns important lessons of freedom, family and Judaism.
