Keeping a baby Alicorn out of trouble is a big job, but Twilight Sparkle has been a huge help with her niece Flurry Heart. So Princess Cadance and Shining Armor decide to create "Auntie's Day" in order to show their gratitude! They gather all of Twilight's friends at the Castle of Friendship--Fluttershy, Pinkie Pie, Rarity, Applejack, and Rainbow Dash--to plan the big surprise. Everypony wants this party to be perfect, but with so many ideas, things get a little chaotic. Can the ponies pull off the best party for the best aunt ever? This beautifully illustrated Little Golden Book is perfect for children ages 3 to 7, as well as collectors of all ages.
