It's Easter! The eggs are decorated, the baskets are ready, and Mr. Twist's Easter pants are looking fly, which means one thing: it's time for the annual Twist Easter Egg Hunt, Ada's favorite family tradition. And this year, her parents are letting Ada hide the eggs! But Arthur, her big brother, thinks the egg hunt is going to be too easy now that he's eleven-so Ada has to do a test hiding to make sure it's super hard or else Arthur will retire from the egg hunt forever! Soon Ada, Rosie, and Iggy are brainstorming about how to find the hardest hiding spot in the history of egg-hiding. This sweet and funny story is all about learning from your mistakes and accepting that sometimes you might fail.
