Boston's Little House Girl Meet Charlotte Tucker, the little girl who would grow up to be Laura Ingalls Wilder's grandmother. Eleven-year-old Charlotte can't imagine living anywhere but Tide Mill Lane. She is delighted when a school for young ladies opens nearby. The prospect of a new baby brother and the reappearance of a long-lost relative combine to complete Charlotte's world. But a new dam connecting Roxbury and Boston turns Tide Mill Lane into a noisy, messy construction site, and Charlotte's parents worry about what this will mean for their family. Across the Puddingstone Dam is the fourth book in The Charlotte Years, an ongoing series about another spirited girl from America's most beloved pioneer family.
