Juniper Jupiter is a real life superhero. Its no big deal. She's super brave, super fast, super strong, super smart and she can even fly, but something is missing. What is a hero without an amazing sidekick? It turns out that lots of people want to be a superhero's sidekick, but none of them are quite right. They're too big, too scratchy, too weird, too scared, or WAY too prepared. Juniper is about to give up, but then she hears a familiar bark... Could it be that the sidekick she's been looking for has been there the whole time? This is a fun and feisty story about friendship from Lizzy Stewart, the winner of the 2017 Waterstones Childrens Book Prize.
