A neat period trifle about the bounding passions of Julia, daughter of Benjamin, a former captain and now shipbuilder on Cape Cod in the 1830s. Julia has been determined her whole life long to ship aboard and sari off some day, and eventually she does manage to work alongside Benjamin--planning, designing, supervising. Then handsome Jason comes along, and in spite of Benjamin's opposition, they marry. But Jason drowns at sea. Julia loses wits and will for a spell, even follows Jason's ghostly voice off Provincetown, but she at last rallies and finally is won by Stephen, who will captain the shipyard's pride, the Crystal Star. So it's out of the slip and a fair wind ahead for both. More of a dinghy than a sloop-but there are those who will enjoy bobbing along with this or its Pocket Books manifestation to follow.
