Things have changed for Samantha. She leaves quiet Mount Bedford for the bustle of New York City and the company of Aunt Cornelia's ten-year-old twin sisters, Agnes and Agatha. This pair is good at getting into mischief, and at bringing Samantha with them. When the three of them visit Grandmary's summer home, their adventure leads to danger on Goose Lake — the same lake where Samantha's parents drowned! Then word comes that Samantha’s neighbor Nellie and her sisters are in serious trouble. It's up to Samantha to save her friends before it's too late. This book is richly illustrated in full color and includes a peek into Samantha’s 1904 world.
