Twelve-year-old Enly Wu Lewis needs to go to band camp this summer. It’ll help him follow in the footsteps of his dad, a musician who died when Enly was too young to even remember him. Enly isn’t sure if he has his dad’s talent, but he wants to find out. There’s just one hitch: The camp is too expensive, and Enly’s mom is saving every penny for his older brother’s college tuition. So Enly sets out to earn the money for camp on his own by busking—playing music on the sidewalk in the touristy part of town. What could go wrong? For one thing, the only instrument he can afford is a melodica, a cross between a harmonica and a keyboard, which he can only kind of play. And for another thing, it’s harder than Enly expected to make serious money busking. When someone drops a winning scratch-off lottery ticket into his tip box, Enly thinks it’s the answer to all his problems. But he’ll still have to face teenage thieves, his disgruntled best friend, a rogue pet pig, and his own family if he wants to achieve his dreams.
