Why parents love it

Curiosity in, screens out.

Every page answers a real question kids actually ask — in warm, simple words, with a bright illustration and a surprising “Did you know?” fact.

🧠

Builds the “why” habit

Feeds natural curiosity and turns everyday wondering into real understanding — the foundation of a lifelong learner.

📚

Makes reading a treat

Short, snackable answers and a picture on every page keep reluctant readers turning pages on their own.

🔬

Facts you can trust

Every answer was independently fact-checked against sources like NASA, NOAA and Britannica — so you never have to second-guess it.

🌙

Perfect for bedtime

One question, one cozy answer. Ideal for a calm “just one more” at the end of the day — no screens, no sugar rush.

🎁

A gift that lasts

A whole library for less than the price of one hardcover — and it never gets lost, torn, or left at grandma's.

“I built Lylo Books for my own kids, who ask a hundred questions before breakfast. I wanted answers that were actually correct, beautifully illustrated, and short enough to read at bedtime — without handing over a screen. Every book is fact-checked and made with love.”

— The Lylo Books team 🦉

Good to know

Questions, answered.

What exactly do I get?

Each purchase is a digital eBook in two formats: an EPUB (great for phones, Kindle, Kobo and reading apps) and a PDF (opens on literally any device). The $19.97 bundle gives you all 12 books in both formats.

What devices does it work on?

Everything. The PDF opens on any phone, tablet or computer. The EPUB works in Apple Books, Google Play Books, Kindle, Kobo and most e-readers. No special app required.

What ages is it for?

Written for curious kids roughly ages 6–10 — short answers a new reader can manage alone, and plenty that older kids (and parents!) still learn from.

Are the facts reliable?

Yes. Every single answer was independently reviewed and fact-checked against authoritative sources (NASA, NOAA, Britannica, museums and .edu/.gov references) before launch.

Can I print it?

Absolutely — the PDF prints beautifully at home if your kid prefers paper.
