About the Book and Author and Illustrator
Renowned physicist Alan Lightman, author of Ada and the Galaxies, turns his focus to light waves in a second picture book story for children.
There’s only one gift Isabel wants for her sixth birthday: a way to see invisible things. She can hardly think of anything else until the day of her party arrives!
Inside the box is a glass prism and a dazzling world of previously invisible colour emerges, lighting up the room around her.

Book Review
the story and it prompted a lot of thinking and discussion
Megan said: I liked this book. I liked the main character Isabel as I have a friend called Isabel in my year at school. I can’t see invisible things. I don’t know why Isabel wanted to see invisible things.
I know what a prism shape is from school, but I didn’t see colours in it. They weren’t invisible as you could see them. I couldn’t see the rabbit as that was invisible! But I could see the dogs as they were not invisible – they both have names of girls in my class so I liked that.
Mum says: I think Megan enjoyed this book, but she was a bit confused. I’m not sure even I understood the science bit at the back, but that’s just an addition to the story.
There was some good words in the story to learn – Megan got mixed up with invisible and Isabel – and couldn’t read Genevieve (which I thought was a difficult choice of name). She didn’t understand why Isabel didn’t want a bike or a castle for her birthday, but wanted something invisible…not sure most children at 6 years old would. I asked Megan if she would like something invisible – but she said ‘what like a window’ I wouldn’t like that! It’s a bit of a hard concept to grasp but hope this feedback is helpful, we did enjoy the story and it prompted a lot of thinking and discussion.
