The Jessie Files

A mysterious hacker is on the loose in Greenfield.

When an embarrassing message between Charla and Daniel goes out to the whole class, Jessie finds herself stuck between her feuding best friends. As she helps Charla investigate how this happened, they find that someone has been tampering with Charla's lawyer mom's computer, and it could spell trouble for her mom’s legal case. In order to keep the culprit from walking free, Jessie and Charla need Daniel’s help. But when some messages go out, they’re hard to take back.

Gertrude Chandler Warner grew up in Putnam, Connecticut. She wrote The Boxcar Children because she had always dreamed about what it would be like to live in a caboose or a freight car—just as the Aldens do. When readers asked for more adventures, Warner wrote more books—a total of nineteen in all. After her death, other authors have continued to write stories about Henry, Jessie, Violet, and Benny Alden, and today The Boxcar Children® series has more than one hundred books.
