Now an instant USA TODAY bestseller!

When Aviva Davis and Holly Martin meet at the holiday pageant tryouts for their local senior's center, they think they must be seeing double. While they both knew they were adopted, they had no idea they had a biological sibling, let alone an identical twin! The similarities are only skin deep, though, because while Aviva has a big personality and even bigger Broadway plans, Holly is more the quiet dreamer type who longs to become a famous author like her grandfather.

One thing the girls do have in common is their curiosity about how the other celebrates the holidays. What better way to discover the magic of the holidays than to experience them firsthand? The girls secretly trade lives, planning to stage a dramatic reveal to their families. Two virtual strangers swapping homes, holidays, and age-old traditions-what could possibly go wrong? Find out in this sweet as a sugarplum and satisfying as a latke middle grade novel by Marissa Meyer, #1 New York Times-bestselling author of The Lunar Chronicles, and Joanne Levy, award-winning author of Sorry for Your Loss and several other books for tweens.
