This enchanting book invites readers to imagine themselves gazing at the night sky from different children’s rooms around the world. Hold the windows on each page up to a light source, and constellations magically appear—celestial creatures that roam the sky before dawn.

What’s Hidden in the Sky offers eight playful riddles that each suggest a different animal constellation hidden in the night sky, depending on the time of year and the viewer’s location around the globe. This utterly unique child’s-eye view of the stars overhead is sure to amaze and delight stargazers of all ages.


"Growing up in a major city in Malaysia, the sky is always canopied with darkness. Nothing shows. How I wish I had a book like 'What's Hidden in the Sky'; the interactive Shine-A-Light brings constellations home. It returns the brilliant sky to children, and even to city dwellers, like myself, who are deprived of the opportunity to ponder the beauty of the universe." -Dr. Yuan-Sen Ting, Associate Professor in Astronomy and Computer Science, The Australian National University

"Aina Bestard takes us on a trip around the world to peer into the night's sky from the vantage point of our kin. The stars have an uncanny ability to spark our imagination and curiosity and What’s Hidden in the Sky brings that spark to life" - Chris Farrie, Quantum Physicist and Author of 8 Little Planets 

“Such a wonderful book! “What’s Hidden in the Sky” does a great job of illustrating the constellations while providing perspective to the young reader, teaching them that different children from around the world will see different stars on the same night. It’s a brilliant way to teach kids how the celestial sphere works and at the same time learn about new places on the globe! Helping them understand star positions and how that relates to your position on Earth - stellar geometry at its greatest!” -Athena Brensberger, Atroathens 

What’s Hidden in the Sky is a lovely book that will introduce children to astronomy through an interactive Shine-a-Light technique. The beautifully illustrated pages draw readers in and the riddles keep children engaged. A perfect bedtime story for space enthusiasts!” - Saana Teittinen-Gordon, Neuroscience Major, @sciencebysaana on Instagram

"What's Hidden in the Sky is exactly the kind of book I longed for as a child obsessed with the cosmos! If you have a child whose eyes twinkle as they peer at the night sky, then Aina Bestard's book will only expand their fascination. With the help of a flashlight, they'll be on their way to discovering their new favorite constellation!" - Katya Echazarreta, Kat Voltage, Electrical Engineer & Science Show Host

Glance out the window from eight locations around the world and marvel at the animal constellations hidden in the night sky above.
