My 11 yr old and I read this together each evening and we loved it. It was full of easy to understand examples of when you may feel angry or upset and also great tips on how to deal with it. My son thought it was great and found it helped him as he could relate to all the the examples and talked through the times that he feels angry. I would thoroughly recommend this book for children of this age and slightly younger. Even though other reviewers have suggested it's good for age 6+, I really don't feel they would get the maximum out of it. It needs to be read with an adult to help the child to understand how to take a deep breath and work out for themselves what really matters and if it's worth getting upset about. One of the best books I've read.
