Mysterious Things

From the creators of the New York Times bestseller Invisible Things, this entertaining exploration of invisible mysteries is a mind-tickling, STEM-friendly invitation to explore the unseen world.

The universe is full of Mysterious Things—lost things, forgotten things, things we don’t know, and even things we don’t know we don’t know! In fact, you might say the world contains more questions than answers! Questions like:

• What do dreams mean?
• What is at the bottom of the ocean?
• Where is that lost puzzle piece?

If you’re ready to begin unravelling these mysteries and more, grab your detective’s hat or slip into your lab coat and come along on an exciting journey to embrace the unknown.

INSPIRATIONAL FUN: Learning about some of the universe’s mysteries—like dreams, heebie-jeebies, dark matter, curiosity, rumors, and so much more—will inspire kids to dream big and explore a world full of untapped possibilities, showing that not everything has been discovered yet.

LIFELONG LEARNING: This vibrant book introduces the idea that there's so much we don't know, turning curiosity and problem-solving into a lifelong adventure and fostering a growth mindset.

STEM THEMES: Packed with engaging content and visuals, Mysterious Things will spark curiosity about science, technology, engineering, and math in a fun way.

PRAISE FOR INVISIBLE THINGS: “Invisible Things is as interactive as you want it to be. Along the way, there are seek-and-finds, mindfulness exercises, and discussion topics, but it also works well as a straight-ahead read-aloud. The experience is somehow simultaneously contemplative and exuberant. It’s a winning, wholly original book.” ―The New York Times
