This week, Joe sits down with legendary children’s author Mary Pope Osborne to celebrate the legacy of the Magic Tree House books and the generations of readers who grew up with Jack and Annie’s adventures. 

Together, they discuss the original spark that inspired the series, how the personalities of Jack and Annie developed over time and the early days of writing for young readers during the rise of early chapter books. Mary also shares behind-the-scenes stories about adapting the series into graphic novels, audiobooks, musicals, and animation, along with the process of designing some of the most recognizable covers in children’s literature. 

The conversation also explores Mary’s writing routine, the books that challenged her most creatively, the incredible memories she’s collected from readers over the years and what it means to see The Magic Tree House continue to connect with new generations of kids today. 

Filled with nostalgia, creativity, laughter, and heartfelt reflection, this episode is a celebration of storytelling, imagination, and one of the most beloved children’s series of all time.
