Needing something to fill up her summer days, Joy seeks out her granddad, who also likes to tinker, for something to do. Together they find the perfect project: sprucing up an old bike for Joy. From hardware stores to garage sales, the two find everything they need to transform this bike, little by little, into something that's truly one of a kind. Ornamented with sparkles, a basket, and a brand-new bell, the bike is finally ready for Joy to ride it all over the neighborhood, filling the air with her own kind of music that exudes JOY.

But when a few kids take notice of Joy's bike, and not in a good way, Joy makes an impulsive decision that ruins the dazzling bike she and Granddad worked so hard on. Joy realizes quickly, however, that trying to fit in can be boring, and it doesn't make her feel JOY. Just maybe, with a heartfelt apology and Granddad's help, she can get back on track to being true to herself. This touching story, told by Sherri Duskey Rinker and Ana Ramírez González, addresses the moments of uncertainty when trying to fit in with the crowd, and exclaims the joyful exuberance of self-expression.
