The falling of the World Trade Center changed the lives of a nation but more so the lives of families facing tragedy. The Bennett family—mother Rachel and twins Samantha and Andrew—lost husband and father Ben when the towers fell and have since struggled to rebuild their lives. They now live in the Victorian cottage Ben left them on Martha's Vineyard.

In this sequel to Windswept, as the twins prepare to enter high school they, and a group of friends, follow clues about a Vineyard legend of missing pirate treasure. Their research leads to a compelling two-hundred-year-old tale that is revealed as they discover more about their own lives and purposes.

Sea Change is an exciting novel combining coming-of-age themes with elements of adventure and mystery. Interweaving two timelines, the novel explores the lives of a young sailor in the 1790s and two teenage siblings in the early 2000s who embark on a journey to investigate a local legend involving treasure greater than gold.
