Andy and Mika are about to take a bite out of the Big Apple.

When the Kudo Kids travel to New York City for the first time, they're ready to hit the ground running and see the sights. But the siblings quickly realize that they're excited for very different reasons--Mika wants to take photos of iconic landmarks and visit a famous camera store, while Andy can't wait to try out an escape room that one of his friends told him about.

Both of their plans get shaken up when they learn that Aunt Kei is in desperate need of assistance as she prepares for an important fashion presentation. Not wanting to pass up an opportunity to explore, Andy and Mika enthusiastically volunteer to help run errands with their cousin, Jenny.

When a very special dress, the centerpiece of Aunt Kei's collection, goes missing, they find themselves on a chase around the city to find it in another unforgettable mystery that will leave readers guessing until the very end.
