Juniper Jupiter by Lizzy Stewart
Juniper Jupiter is a real life superhero. It's 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 . . . will Juniper ever find the perfect one? This is a fun and feisty story about friendship and learning to value what you already have.
