Rachel Bright and Jim Field have collaborated on several books. The two I have read, The Lion Inside and The Squirrels Who Squabbled are Lesson Books. Still, there is a fun 
story to go along with it as well.
The Lion Inside will be my first review. We have a tiny mouse who has a tiny voice. They want to be big. After all they are tired of being sat on, ignored, stepped on and so forth. But they are also very shy, very nervous and not very brave. Now, the lion, on the other hand, demands attention. That roar is what mouse needs! Summoning all their courage, off they go to the lion’s rock. There, mouse learns more than they bargained for! This is a cute story how we have both “the mouse” personality and “the lion” personality inside of us.
I guess I am not a fan of arguing/squabbling books. The Squirrels Who Squabbled as a story has been done before. The illustrations are fun and show the crazy adventures the squirrels find themselves in, but “working together” needs a slightly less obvious ending. Maybe next time someone can write one that says, “They never learned their lesson to share/work together” so they lived a lonely, miserable life?
The rhyming help make these stories easy to move along with. There are some cute illustrations that show the story. There are the right amount of details and the right colors used to accent the points made.
The third book in this group is The Koala Who Could. This time we learn about change and adapting (or not). I am looking forward to reading, if I find a copy, but I do not think I will be actively searching for it.
