The language of Butterfly Brain is rich and full of vivid imagery . The absolutely stunning illustrations elevate the story further and intensify its emotional effect on the reader and are just the right blend of the darker, shadowy images of Gus's fears and the softness and warm colours of his positive memories about those most important to him. The gentleness and warmth of the final pages are powerful, overwhelmingly comforting and sensitive. -- Jenny Caddick ― Reading Zone
The story is one of grief, loss but ultimately recovery as Gus can finally talk to his dad and grandmother about the secret he's kept locked inside himself. Despite the weight of issues being discussed, the verse retains its spark, offering reassurance and pointing the way to a brighter future for Gus and anyone facing the loss he's experienced. Gwen Millward's illustrations are equally accessible and emotionally true and it's a book that will prompt young readers to examine their own feelings and fears, and to understand why anger can be a response to sadness or anxiety. -- Andrea Reece ― Books for Keeps
