The Boxcar Children are thrilled when they discover that hockey star Kevin Reynolds will be coaching a girls' hockey team right in Greenfield. As soon as practice begins, however, strange things start to occur.

Gertrude Chandler Warner was born in 1890 in Putnam, Connecticut, where she taught school and wrote The Boxcar Children because she had often imagined how delightful it would be to live in a caboose or freight car. Encouraged by the book's success, she went on to write eighteen more stories about the Alden children.
