A new suspenseful duology opener from New York Times bestselling author Margaret Peterson Haddix about a girl who learns she's part of a network of time travelers who want to change the world.

When Maisie’s mom drops an old phone into her lap, Maisie can’t believe her luck. Finally, she’ll be able to text people from school and watch the videos everyone’s talking about!

Unfortunately, her mom also breaks the news that their family will be moving from Ohio to Maryland for the summer to take care of Maisie’s great-aunt Hazel. Maisie’s only getting a phone because she’ll be taking care of her younger siblings for the entire trip. With that, Maisie is ready to give back the phone.

Then the first puzzling text comes in.

Between the mystery texts and a not-quite-empty book from Great-Aunt Hazel, Maisie finds herself thrown into the world of the moonleapers. As she slowly learns more about this secret society, will she be able to commit to everything they require? And will she be able to help the Moonleapers accomplish their mission in time?
