Being the middle child has its ups and downs. But for Grace, an only child who was adopted at birth, discovering that she is a middle child is a different ride altogether. After putting her own baby up for adoption, she goes looking for her biological family, including Maya, her loudmouthed younger bio sister, who has a lot to say about their newfound family ties. Having grown up the snarky brunette in a house full of chipper redheads, shes quick to search for traces of herself among these not-quite-strangers. And when her adopted familys long-buried problems begin to explode to the surface, Maya cant help but wonder where exactly it is that she belongs. And Joaquin, their stoic older bio brother, who has no interest in bonding over their shared biological mother. After seventeen years in the foster care system, hes learned that there are no heroes, and secrets and fears are best kept close to the vest, where they cant hurt anyone but him.
