Seventeen-year-old Mira has always danced to her own beat. A music prodigy in a family of athletes, she'd rather play trumpet than party -- and with her audition to a prestigious jazz conservatory just around the corner (and her two best friends at music camp without her), she plans to spend the summer focused on jazz and nothing else.

She only goes to the warehouse party in a last-ditch effort to bond with her older sister. Instead, she falls in love with dance music, DJing... and Derek, a gorgeous promoter who thinks he can make her a star. Suddenly trumpet practice and old friendships are taking a backseat to the packed dance floors, sun-soaked music festivals, outsized personalities, and endless beats of the EDM scene.

But when a devastating tragedy plunges her golden summer into darkness, Mira discovers just how little she knows about her new boyfriend, her old friends, and even her own sister. Music is what brought them together... but will it also tear them apart?
