Publisher: Little, Brown Books for Young Readers (June 10, 2014)

As seen on the hit animated series My Little Pony: Friendship is Magic!

Learn the history of Princess Celestia and Princess Luna by reading the diary they kept when they were younger.

Inspired by Celestia and Luna, the pony friends Princess Twilight Sparkle, Pinkie Pie, Rainbow Dash, Fluttershy, Rarity and Applejack share a diary of their own! Read their entries–as seen on the show–and then write some of your own friendship observations in the book, too!
