The Aldens chart a course for their next adventure – Australia and Antarctica!
As the children tour the famed Sydney Opera House, their next puzzle – and its key – falls right into their laps. They need to find the rightful owner of a rare Australian coin. Using their knowledge about Australia, the Aldens find the coin’s owner, but a saboteur is again hot on their heels and nearly spoils their hard work.
Next up, the Aldens travel to frigid Antarctica, where they need to return an artifact to the hut Shackleton used on his expeditions to the South Pole. The trip is a success, but when they Aldens return, they learn the identity of the person who has been trying to ruin their plans. Will the saboteur keep them from returning the seventh and final artifact.

Book 4 of the book club with my nephew. These books crack me up now, but I would have loved them as a kid. In this book the kids flew in a private jet to Antarctica! There's bad guys to foil and trick, and some good lessons in history and archeology that kids can learn while reading. These are fun books!

Great fun! The Aldens visit Australia and Antarctica in this volume. Their race around the world continues, and they experience some sightseeing while they travel. I love how this mini-series exposes kids to other countries, cultures, and foreign landmarks.

Created but not written by Gertrude Chandler Warner. These books are for children in elementary school. My first book, The Boxcar Children by Gertrude was fantastical, and read to me in class by my 1st grade teacher. The books started my love for fiction mysteries. Ironically, Warner was called to teach first grade, mainly because male teachers were being called to serve in World War I.

This book is number 4 in a 5 book series: The Boxcar Children Great Adventure. My suggestion is to start with number 1. In fact, if you have never read the The Boxcar Children books, you should start with book #1.

Gertrude did not write this book, this book is a creation of her prior writings. In fact, people have been making money off of her children's stories as there are hundreds of stories about the Boxcar Children! Gertrude Chandler Warner (April 16, 1890 – August 30, 1979) was an American author, mainly of children's stories. She was most famous for writing the original book of The Boxcar Children and for the next 18 books in the series. In my opinion, none of the other books compare to the writing of Gertrude.

This is the best of the miniseries, but I wish that as a whole, these five books were given space to breathe -- I mean, seven continents of travel in seven books would have made more sense and allowed for more thought and consideration about these destinations and the artifacts they're carrying, no?
