Portsmouth, England,1760. Patricia Kelley, the illegitimate daughter of a wealthy Barbadian sugarcane planter, falls from her imagined place in the world when her absent father unexpectedly dies. Raised in a Wiltshire boarding school sixteen-year-old Patricia embarks on a desperate crossing on a merchantman bound for Barbados, where she was born, in a brash attempt to claim an unlikely inheritance. Aboard a merchantman under contract with the British Navy to deliver gunpowder to the West Indian forts, young Patricia finds herself pulled between two worlds -- and two identities -- as she charts her own course for survival in the war-torn 18th century.
