Following the Boxcar Children's 5-book "Great Adventure" and their 4-book "Creatures of Legend" saga, Albert Whitman & Company offered up a third mini-series entitled "Endangered Animals." The tagline for this planned 4-book series reads: "Henry, Jessie, Violet, and Benny are helping endangered animals all around the world!" The first two books were issued in April 2022, with the second two books set to be published thereafter. Having grown up reading The Boxcar Children in my school library, and having recently re-discovered the enjoyment of this series with the two animated movies and the 5-book and 4-book mini-series, I figured I would give this series a go as well. It did not disappoint.
The Big Spill Rescue sets the stage for the Alden children to develop a desire to help save endangered animals. The four kids are visiting Port Elizabeth, a city in an unnamed state, but one that must be along the coast, as there is a lighthouse that is still used to ensure ships do not come too close to shore at night and run aground. (Note: there is a Port Elizabeth, New Jersey, but it is unlikely this is the town, since this unincorporated town is not located along the ocean coast.) The children are introduced to the daughter of their father's friend, who shares with them her love for helping protect endangered animals. When an oil spill occurs as a result of a tug boat running aground one night - the very night the lighthouse somehow malfunctions, it gives the Alden children an opportunity to not only help rescue the birds and other animals affected by the spill, but it also gives them the chance to solve the mystery of why the lighthouse was not working properly. The mystery, as with most Boxcar Children stories, is fairly basic, and while there are a couple of suspects, there is one very obvious ones - it is simply the matter of Henry, Jessie, Violet, and Benny finding the right clues to lead them to the culprit. Henry is the one who actually figures it out, with a little observational help from Jessie and Violet. By the end of the story, Kayla (the daughter of their grandfather's friend) invites the Alden children to travel with her and help other endangered animals around the world - hence, the name of the mini-series!
Mystery of the Spotted Leopard takes the four young sleuths to India, where they will assist Kayla with research she and her organization, Protectors of Animals Worldwide ("PAW"), are doing on the spotted leopard population that live up in the Himalayan mountains. This time, the region used for the story (the city of Leh in Ladakh) actually exists in the real world. The group actually travels to a small village higher up into the mountains, where, realistically, the children must adjust to the lower levels of oxygen at such high altitudes. It is here that one of the spotted leopards the research time has been monitoring disappears, its GPS collar cut away from its neck. The research team is concerned that one of the local farmers may have killed the leopard to keep it from stealing any more of their stock, or that a poacher had come to claim the endangered animal as a prize for its beautiful coat of fur. Once again, these four very self-sufficient children step in and follow the clues that lead them from suspect to suspect, until they narrow it down to the only possible culprit - the least likely of people for them to have believed would commit such a crime! Of course, the leopard is rescued with little harm done, the culrpits arrested, and the Alden children are ready to return home to their grandfather and their dog - but not before they are told that there are more adventures yet to come!
Unfortunately, those last two adventures in the Endangered Animals mini-series never saw print. Books 3 (Mystery of the Vanishing Forest) and 4 (The Great Reef Rebuild) were both solicited, with covers provided and all; however, before the date of publication hit, both books suddenly became "unavailable," and the release dates were changed to 2079! I'm not sure why, but the print version of these books never saw the light of day, and the only versions available are audio books. A very small portion of the third book (and when I say "small," I am talking about only 4 pages!) was available as a preview at the end of Spotted Leopard; but, other than that, no hard copies were ever printed or sold. This is a real shame, as it left readers with an incomplete series (only 2 of 4 books) in printed form. One has to wonder if the series was no longer profitable for Albert Whitman & Co., or if the publisher itself was simply not doing well, which could have been the reason the entire Boxcar Children property was sold (see below for more information on that subject).
Craig Orback provided the art for Big Spill and Spotted Leopard, and it appears he also painted covers for books 3 and 4, which can be seen on sites such as Amazon and Barnes & Noble, but only available now as audio books. Orback also did the internal illustrations for the first two books, so one has to wonder if he did any internals for the last two books, which, because the books were never published, are sitting on someone's desk unused at this point. I'm not a fan of audio books (I prefer holding books in my hand as opposed to listening to them while I drive), so I am unlikely to ever purchase the last two books in the series - which is disappointing, as I would have liked to have seen where the next two books were planning to take the Alden children. The descriptions on Amazon indicate the third book would take the kids to Sumatra, where they have to stop the destruction of part of the rain forest there, which is the habitat to many endangered species. The fourth book would take them down under to Australia, where they have to fight to save the lives of underwater creatures and their natural habitat there. But, alas, it is unlikely either of these stories will ever see a print version, in which case, I am left with an unfinished mini-series that will have to remain incomplete on my shelf.
What is even more disappointing than all of this is the fact that another mini-series was solicited to begin the very next year (2023), which was called the "Summer of Adventure." The first book, Legend of the Hidden Treasure, would have had the Alden children helping their Aunt Jane move to the coast, where a boat called the Alden Explorer washes ashore. In the boat, they find a mysterious journal that talks of hidden treasure and a secret society, which sends the kids off on another mystery-solving adventure. A cover, painted by illustrator Karen De La Vega, was provided with the solicitation. A second volume to the series, titled Secret of Superstition Mountain, would have followed, wherein the children are led by the journal to return to the site of their very second book - Surprise Island! There, they learn more about the secret society and what it really means. What is odd is that there is no image of the cover to this second book in the Summer of Adventure series; however, a search online reveals a Boxcar Children mystery of this title with a cover by De La Vega, but it is listed on The Concord Bookshop website as book 164 of the ongoing series (The Concord Bookstore - Boxcar Children 164). There, it lists the date of publication as 2079 (same as that of books 3 and 4 of the Endangered Animals series), which means the book will likely never see print. Such a shame, as the titles and brief synopses for these two books actually sounded fun!
I do note that there are two graphic novels being solicited to be released in August 2026. The first appears to be a retelling of the children's very first adventure, simply titled The Boxcar Children. The second graphic novel is titled Shipwreck! and potentially could be a retelling of the second book in the series, Surprise Island. With my love of both children's mystery series and graphic novels, you can rest assured I will be getting both of these graphic novels.
Some searching online does reveal that Random House Children's Books purchased The Boxcar Children property from Albert Whitman & Company, which is likely why those last solicited books never saw print. As it currently stands, the only new items coming from Random House at this time are the scheduled graphic novels. Some further digging reveals that the ongoing series did continue past book 160 (or, at least, was scheduled to), with books numbered up to 164, including:
160 - The Mystery in the Magic Shop (alleged release date of 2022)
161 - The Raptor Rescue (alleged release date of 2022)
162 - The Code-Breaking Mystery (alleged release date of 2023)
163 - X Marks the Spot (alleged release date of 2023)
164 - Secret of Superstition Mountain (alleged release date of 2023)
165 - The Supermarket Mystery (simply says "coming soon")
166 - Sports Day Sabotage (simply says "coming soon")
Based on this list, it appears the two "Summer of Adventure" stories were integrated into the ongoing series as books 163 and 164, with Legend of the Hidden Treasure retitled as X Marks the Spot. Books 160 and 161 are available in print form, as well as audio, on Amazon. However, beginning with book 162, the release dates show as "2079," the indicator that they are likely not to be published any time soon, if ever at all. Random House has established a new website for the series (The Boxcar Children), where the graphic novels are advertised, as well as early books from the series and repackaged specials are offered. I see no indication yet of whether books 162 through 166 will be offered, and whether the series will continue after that; nor do I see anything that might indicate Random House is looking to reboot the series (aside from the graphic novels). I supposed we will simply have to wait and see what the new publisher has in store for this long-time children's series.
RATING: 7 cups of dirt tea with salt and yak butter out of 10 for taking the Boxcar Children on an all-new world-hopping adventure to save endangered animals, giving readers an opportunity to learn about numerous animals that have nearly gone extinct!
