Cleo & the Silent Hummer. Jitter Jumpers, #2

At fifteen, Cleo Thorne is a finely tuned instrument of perfection. Her life is a meticulously orchestrated ballet of camera flashes, glossy magazine covers, and the intoxicating roar of applause. But beneath the shimmering surface, a storm is brewing. A persistent, bone-deep vibration, the "Quiet Hummer", has begun to haunt her every move. As the noise grows louder, threatening to shatter her curated reality, Cleo must decide: can she maintain the mask of perfection, or will she let the Hummer reveal the truth of who she really is?
