As with all series, I wish Little Unicorn Is Angry was in a collection with the other emotions/feelings Little Unicorn will deal with. I think a nice boxed set with the individual books would work best. Currently Aurelie Chien Cheow Chine has Little Unicorn Is Scared as well as Angry out and in January 2020 Little Unicorn Is Sad and Little Unicorn Is Shy will be published.
While perhaps it could be a bit “sweet” for some, this story about feelings (and anger in particular) is actually well done. The breathing exercises at the end are a good way to help a child to stop, pause and think about their anger and find a constructive way to blow away whatever is causing it. And while Little Unicorn wants to throw a tantrum (and there are starts of that) the reward of the breathing shows the more constructive manner of dealing with it.
The use of colors to show the different feelings. This, for some reason, amused me. The rainbow mane when all is well “drains” into red, yellow, pink, orange, green, blues. This physical change helps show how Little Unicorn is not only feeling but allows your child to be able to guess before going to far into the story. The art itself is quirky and cozy. The cartoon aspect will most likely endure them to readers of all ages.
And while dealing with emotions is not a new subject, and the story has a more modern take on dealing with them, there is the classic feeling of the nuclear family. You get the best of all worlds in Chine’s story.
