The Mysteries About True History's podcast is back for season two.

If you're a kid who would love to travel through time to solve cool mysteries,

perplexing puzzles, and tricky riddles,

then this podcast is the perfect audio treat for you.

Every week, join me, Molly, and my best friend Max,

as we take our problem-solving skills to amazing places like ancient Egypt,

ancient Greece, or the Galapagos Islands in 1875 to help out the one and only Charles Darwin.

We never know where we're going to wind up or what we're going to find, which is all part of the fun.

So put on your time traveling shoes and listen as a family.

You can listen to mysteries about true

histories on Apple Podcasts, Spotify, or wherever you listen to podcasts.
