A vivid story of Puritans in a Massachusetts Bay Colony settlement and the exciting adventures of the Partridge family in particular. Life is never dull to young Seaborn, or to Comfort, his sister. Hunting wild turkeys with Know-God the Indian boy, encounters with bears and wolves, and rumors of Indian raids are everyday dramatic events.

Puritan Adventure centers around the widowed Charity Cummings coming to the Massachusetts Bay Colony to live with her sister's family. Unaccustomed to the more austere New England life, she serves as a colorful foil through which to view the nuances and complexities of colonial Puritan existence.

Noted for speaking her mind and for what to the Puritans seems her flamboyant mode of dress, Charity becomes a bit of a thorn in the side of community authorities. Charity's more easy-going nature is contrasted throughout the story with the sterner outlook of a number of the Puritan settlers, particularly the so-called "Tithing Men" charged with the business of getting into other people's business in the name of proper behavior and decorum.
