Henry, Jessie, Violet, and Benny didn't think the old trunk in their house held anything interesting. But an unusual statue they find inside leads them to the Reddimus Society, a secret guild dedicated to returning lost treasures to where they belong. Now the Aldens must help their new friends by traveling across the country with the statue and six mysterious boxes! Can the Boxcar Children keep these seven treasures out of the wrong hands?

The Aldens are spending their first week of summer at Camp Quest in Colorado. The children are excited to learn about fossil-hunting and paleontology from renowned scientist Dr. Iris Perez. But strange events at the camp make them wonder if the legends of a bigfoot-like creature roaming the valley might be more fact than fiction. Can the Aldens help Dr. Iris figure out who - or what - is causing such a stir?

When an oil spill takes place off the coast of Connecticut, the Aldens are happy to volunteer to help clean up the animals affected, including a rare species of shore bird. But could more have been done to prevent the spill? As the Aldens take up the case, it leads them on an adventure to help other endangered animals around the world.

Lucas and Clara search for Queen Tasha's missing emerald. On their exciting adventure, they travel to all the main attractions of Wrenly: Primlox (the island of fairies), Burth (the island of trolls), Crestwood (the island of dragons), Hobsgrove (the island of wizards), and the beautiful Mermaid's Cove. King Caleb has promised to reward the person who finds the precious stone, and Lucas and Clara are determined to search the entire kingdom until they find it!

Before they were the Boxcar Children, Henry, Jessie, Violet, and Benny Alden lived with their parents on Fair Meadow Farm. Although times are hard, the Aldens are happy - “the best family of all,” Mama likes to say. One day, a blizzard hits the countryside, and a traveling family needs shelter. The Aldens take them in, and the strangers soon become friends. But things never stay the same at the farm, and the spring and summer bring events that will forever change their lives.
