These children’s mysteries by Gertrude Chandler Warner were first published in 1924. The first book in the series, The Boxcar Children, was named one of the “Top 100 Chapter Books” of all time in 2012. The series now includes over 100 titles, although only the first 19 were written by Warner. Each story is a fun, fascinating mystery kids love to try and solve. We love the focus on family and the wholesome values they teach.
