Book available for primary age children

I’ve written a book for children based on my Facebook group, The Adventures Of the insulin Gang Travelling Bears. It’s a story about a teddy bear being taken into Hospital by a Diabetic Nurse to visit a newly diagnosed child. The bear has an element of magic and reassures and educates the child. It’s available on Amazon.
Read the reviews to see what others are saying. I’m a novice author. Amazon are making a huge profit from my book which my daughter illustrated. It’s about wanting to make a difference.
