The Stones of Green Knowe
L. M. Boston, Peter Boston
(HMH Books for Young Readers, Jan. 1, 2006)
This last installment of the beloved series recounts the long-ago beginnings of Green Knowe, a time when Roger, the son of a Norman lord, was the first child to live in the grand old manor. Roger finds some ancient stones on the grounds, which magically transport him back and forth in time so he can meet and befriend Toby, Linnet, Susan, and Tolly--the future inhabitants of Green Knowe and the heroes of the five other magical books in the series.
