There are few mediums which effectively reach the broad demographic that Brodie has with Rise Up. The themes and messages within this story are so important, and Brodie has presented them in such a way that speaks to adults, but can be understood by pre/young teens alike.
The overall plot itself is not particularly deep, but I don't say that as a bad thing (many timeless movies are plotless) because regardless, the story takes you on an adventure that weaves perfectly within reality and fantasy.
Which brings me to what I really love most about this book, and that is the unique way in which Brodie has given us a story about two sisters and their imagination fueled adventures and then let us step into their minds so we can see what they see. During these fantastical moments is when we experience not only their creativity, but their mental health and social struggles which bleed into their projections, and ultimately how they deal with them. It reminded me very much of Sucker Punch, only a more kid-friendly version.
I would recommend this book to pre/young teens and young adults. Though, because of the complexity of some themes, I'd recommend reading it yourself before giving it to anyone too young, just so you are prepared to have any conversations this book is bound to inspire, as I feel the Author intended.
