The picture book “Two” by Kathryn Otoshi And Illustrated by Kathryn Otoshi is a sequel of a picture book called “One”. Is a book about how odd and even numbers get along together. Number 1 and 2 were best friends but suddenly 1 said he is playing only odds now. So number 2 started feeling blue and green. So the number 2 started cracking. When the number cracked it formed a < > sign and he realized he can be anything odd of even. Then 2 bumped into 1 and they started to talk to each other. Then they became friends again. I rate this book 3 out of 5 and I think this book is best for 6-8 years old children. I liked this book illustration because the textures from the brush. Also I think this book has a very suitable drawing on each page.
