The Very Nearly Honorable League of Pirates: Magic Marks the Spot (audiobook)
This story is about a young girl who wants to be a pirate. But The Very Nearly Honorable League of Pirates will only admit boys, and her father, who is an admiral, insists she go to finishing school. That’s the last thing she wants. Fortunately, she’s not entirely alone. She travels with a magic gargoyle who also wants to be a pirate. They go to finishing school together and plan their escape. The narrator is very talented and the voices are all different and engaging.
Chronicles of Narnia
This entire series is really good. There are some very clear Christian messages in the book, but they aren't so heavy handed that someone who's not a person of faith would be turned off by. So far, we've listened to The Magician's Nephew, The Lion, the Witch and the Wardrobe, and The Horse and His Boy. All of which were very good.
The Secret Zoo
This was a fun listen.
Wow In the World (podcast)
This science focused podcast is extremely interesting and animated because it’s created for kids, but parents will learn quite a bit as well. It’s a whole family experience. Each episode is about 20 minutes long, so if you have a short trip, this might be the perfect thing to keep kids happy on the way.
