Two is a picture book written and illustrated by Kathryn Otoshi. The main theme of the book is friendship and courage. In the book, One and Two are best friends and always stick together, until Three comes along. Two finds herself spending less time with One when Three is with One, and Two gets jealous! The other even numbers quickly comfort two, and make cruel statements about the odd numbers. The odd numbers disagree, and it turns into an all out fight! However, Two quickly steps up and tells everyone that there is no need to fight and that you everyone can play with whoever they want. Three apologizes to Two, and at the end of the day, One and Two are still friends, and all is well. The message of the book is that it’s okay for you to have more than one friend, that you can always meet with new people, and it is possible for everyone to get along. I really enjoyed the book. The illustrations were very pretty and creative. Overall, this book was really clever and funny, I would definitely recommend this book to a friend.
