It's Mila's first day of school, but mixed with excitement is worry. What if she can't find her classroom? What if no one likes her? What if she's too nervous to speak up? With a little advice from her brother, she learns that she has everything she needs right in her Invisible Backpack: an Invisible Microphone to help her find her voice, an Invisible Flashlight for when she's feeling lost, an Invisible Net to catch her if she falls, and much more. Her pack is bottomless! The Invisible String is the very first thing that she puts in her pack--and each time she uses it, it gets bigger and better.

Patrice Karst, the bestselling author of the modern classic The Invisible String, gives readers the tools to confront every obstacle by teaching them to always hold onto their inner strength, to put on their Invisible Wings...and fly.
