The Boxcar Children
In the subsequent books, the children encounter many adventures and mysteries in their neighborhood or at the locations they visit with their grandfather. The majority of the books are set in locations the children are visiting over school holidays such as summer vacation or Christmas break. Only the first 19 stories were written by creator Warner. Other books in the series have been written by other writers, but always feature the byline "Created by Gertrude Chandler Warner". The recent books in the series are set in the present day, whereas most of the original books were set in the 1940s and 1950s.
