This lyrical picturebook features a multigenerational, multicultural (Latinx and Asian), and multilingual (English, Spanish, Lao, and Punjabi) family. Leo and his gender-non-conforming sibling, Luca, love playing superheroes together. In a world where shapeshifting and climbing towers are common superpowers, how can languages be a superpower? Leo and Luca go on a journey shared with their families and witness how language is a superpower that allows them to travel through time, connect with their ancestors' past, and how it is a powerful inheritance. This is a story about heritage languages as legacies and resistance.
