In the novel The Witch of Blackbird Pond, Kit is originally living in Barbados but has to move to Wethersfield, Connecticut after the death of her grandfather and an attempt by an unsavory and elderly man to marry her. The action of the novel takes place almost entirely after Kit has left her original home of Barbados.

Later in the story, there is an instance where Kit is saving Hanna from a mob that believes she is responsible for an illness that is sweeping the town. As Kit and Hanna are fleeing, they encounter the Dolphin, the very ship that brought them from Barbados. Nat, the captain's son, offers to take them on board once again. Kit, however, stays to take care of her cousin, Mercy, who is gravely ill.

It is here that it might have been wiser to go back to Barbados, as Kit immediately after finds that Mercy's fever has broken and the town is accusing her of witchcraft. But after Nat returns, Kit's name is cleared, and she soon returns to Barbados all the same.
