When the Cloud Talks

The Adventures of Ellie & Cloudie 

Through Ellie’s endless questions, the story explains what the cloud does, how it helps, and why it’s nothing to be afraid of. Technology becomes understandable without losing the magic of story time. This book explains the cloud the way kids naturally learn: by asking questions and getting honest answers.

Tech, Untangled

Why This Book Matters

Your kid asks how the internet works. You panic. You say something about "the Cloud" and pray they move on. But when kids don't understand how tech actually works, they can't spot the dangers. They don't know what the Cloud really is, where their stuff goes, or why clicking random links is a bad idea. Marc's books fix that. They explain the tech kids use every day in a way that makes sense, keeps them safer, and saves you from the awkward "uh... I don't know" moment.
