Picture book · Ages 4 to 8 · English and Spanish
Two stories in one book.
Read Goodnight, Otto front to back and it’s Bob’s night in the tent. Turn the book over, read the same pages back to front, and it’s Otto’s. Same words, two children, two sides, and a lesson in seeing the other one that a child learns by turning the book instead of being told.

Bob’s cover. Front to back, it’s Bob’s night.
How a two-way book works
One book. Two sides. The same words, read both ways.
Every Bob & Otto book is a reverso: the lines are printed once and read twice. Forward, in order, they are Bob’s story. Backward, in reverse order, the very same lines are Otto’s. Nothing is hidden on a second page. The other side was there all along; it just hadn’t been read that way yet.
Read it forward
Bob’s side, front to back. He hears half a sentence, sees a laugh, counts two friends, and decides what it meant.
Turn the book over
The back cover is a front cover too. Same pages, same pictures. A sparrow on every one of Otto’s pages shows which side you are on.
Read it backward
Otto’s side. Line by line in reverse, the same words tell what he meant. Neither boy was wrong; each had half of the same afternoon.
Why it works: perspective-taking a child can hold
Between four and eight, children are learning that other people have thoughts and intentions of their own, and that one moment can be understood two ways. Psychologists call the skill perspective-taking; in the CASEL framework it sits under social awareness. Most books tell a child to see the other side. These hand it over: the child turns the book and finds it, which is why the lesson never feels like one.
What the books practise is a habit, not a moral: before you decide what someone meant, ask how they heard it. It is the move that ends a playground quarrel, and later a grown-up one.
“Seeing the same story two different ways also helps to teach children lessons that I think are difficult to convey in any other way.” — Deb Preston, Children’s Book Review
The psychology and the craft behind the series, with sources →
- About a hundred words each way. Short enough for bedtime. Twice.
- The last page is the first page. Every book opens and closes on the same line.
- Find the sparrow. It sits only on Otto’s pages, so a child always knows whose side they’re on.
- One question at the end. What did the other boy mean?
Five books. Ten stories.
Each one is a small, ordinary misunderstanding between two best friends, told from both sides. Start with any of them; Goodnight, Otto is the readers’ favourite.

Bob's way · read the left page first
1 of 3
That was Bob's story.
Now turn it over.
Same pages, same words. Read them the other way and they belong to Otto.
Same six lines. Two stories.
Every Bob & Otto book works like this.
Forward, Bob wanted to go higher. Backward, Otto was there the whole way down. Neither of them was wrong — they just had different halves of the same afternoon.
Free to print and copy for home, classroom and library use.
How to fold it — one cut, no glue
- Print on one side, landscape, at 100% — or "fit to page", it folds the same.
- Fold the sheet in half the long way, then unfold it.
- Fold it in half the short way, then fold each end back to the middle, like a fan of four.
- Cut along the dashed line — only across the two middle panels.
- Open it, fold along the long fold, and push both ends in toward the middle. The cut opens into a little book. Bob's cover is on the front; Otto's is on the back.
Hear them read aloud.
Every book in the series, read aloud, four to five minutes each. Press play and it plays right here; the pages turn on screen, so a child can follow along. Read it Bob’s way first, then turn the book over for Otto’s.

You're on the list.
I'll write when there’s a new book or a new mini book. In the meantime, both mini books are free to print:
Meet them
Tap anyone to hear them in their own words.
- My favorite color is red. That’s why the stripes.
- I hear things fast. Sometimes faster than they were said.
- I’m learning to hear the whole thing.
- Otto is my best friend.
- My favorite color is green.
- I say things slowly. Sometimes too slowly.
- I’m learning to say the important half first.
- A sparrow follows me around. I don’t know why.
- Bob is my best friend.
- She arrived at school on the day of book three.
- She spent a whole morning hearing about Bob before she met him.
- Her name reads the same backwards. So do theirs.
- It sits on every one of Otto’s pages, and never on Bob’s.
- Nobody knows why it follows him. Not even Otto.
- Find the sparrow and you’ve found your starting page.
Why I made these
I'm Jesper K. Lassen — Danish, a mentalist with more than a thousand performances behind me, and the founder of VEN Method. My whole working life has been about what one person notices and another one misses.
Children carry home bad feelings they never needed, because they heard half of something and decided the rest. I wanted a book that doesn't tell them to see the other side — it hands it to them, and they turn it over themselves.
