Teenager Boo Meadows has pink hair and a very vivid imagination - she has trouble separating from the real world.
In her daydreams, she dances beautifully at balls or fights monsters as a magical girl. In reality, she has a complicated home life, work stress, school stress and a wicked crush on the girl of her dreams.
When a new student, Mimi, arrives at school, Boo starts exploring a side of herself that she never considered before. As she grows closer with Mimi, it may finally be time for Boo to face reality . . .
Who is the real Mimi? The one in her dreams? Or the one in real life?
Rainbow! is perfect for fans of Heartstopper and Magical Boy, full of heart, adorable illustrations and a storyline that any teenager can relate to!
