Nelly and the Flight of the Sky Lantern

Sometimes secrets are hidden in the most obvious places. When Nelly returns home to discover that her mother has mysteriously disappeared, she vows to stop at nothing until she's found her. Climb to the tops of the clouds in a laundry basket? Why not? Dive to the depths of the ocean in an oversized tin can? Of course! Leave her turtle, Columbus, behind? CERTAINLY NOT! He's her best friend, what an awful suggestion. Together they will find the answers!
