When her neighborhood decides to throw a block party, Nickelodeon star JoJo Siwa has the best idea ever: she'll perform her hit song "Boomerang" as a highlight of the big summer bash. With her crew of friends behind her and the support of her trusty sidekick BowBow, JoJo's sure their summer will be as sweet as it gets. Then she meets Grace--the new kid on the block with tons of talent to offer--and JoJo knows her plan for a rockin' party is complete!

But Kyra, resident mean girl and head of the party-planning committee, has other ideas. JoJo doesn't know why Kyra dislikes Grace, but it soon becomes clear that she'll do anything to exclude JoJo's new friend. When Kyra's jealousy of Grace threatens to ruin the entire block party, JoJo knows it's time to rally her Siwanatorz and save the day. After all, being a Siwanator means--above all--being kind. And even bullies aren't always what they seem . . .
