Sumi's mother can speak two languages, and she can switch between them with lightning speed. Could it be that Sumi's mother possesses a superpower? Does she have two tongues in her mouth? Sumi can only see one. Reveling in her mother's abilities, young Sumi recalls the story of her mother's migration and how it led her to grow two "tongues". Sumi also shares that some family members have even more tongues than her mother does! And what about Sumi? Where might her language journey lead? In a sparkling debut authored by a 16-year-old daughter of immigrants, this ode to the power of multilingualism gives voice to the lasting benefits of speaking with more than one tongue.
