When Vietnamese American Freddie Lo finds herself in Vietnam for the first time since she was little, she's not quite sure how to feel. The memories of her extended family are more like distant echoes; she has a tough time speaking Vietnamese; and she can't help but feel like she just isn't Vietnamese enough. Still, this is her chance to reconnect with her family, especially her Ong ngoai — or grandfather — who is receiving a big award.

That's when Ong ngoai reveals his secret: He knows the location of an ancient legendary crossbow, one with the power to decimate armies — and he's hidden it away from those who intend to use its magic for evil. But when Ong ngoai is kidnapped, it's up to Freddie, her cousin Lien, and a mysterious boy named Duy to get to the crossbow before it ends up in the wrong hands.

In this Indiana Jones-style adventure, listeners will travel through Vietnam — from its seaside villages, to the swamps of the Mekong Delta, to the majestic Marble Mountains of Da Nang — as Freddie learns what it takes to be a hero.
