Sierra Grace Jackson aka "Gracie" 

 

born and raised in Brooklyn, Gracie is celebrated the world over (and even galaxies far, far away) for her genius-level intellect, fearless imagination, endless compassion, and relentless adventurous spirit.  She speaks eight hominoid languages (including English), three off-world Voosurian dialects, Rexish (Cretaceous dino-language) and is working on whale-song... when not in Mr. Grant's second grade classroom.
