Fifteen-year-old Mari Pujols believes that the baby she's carrying will finally mean she'll have a family member who will love her deeply and won't ever leave her—not like her mama, who took off when she was eight; or her papi, who's in jail; or her abuela, who wants as little to do with her as possible. But when doctors discover a potentially fatal heart defect in the fetus, Mari faces choices she never could have imagined. Surrounded by her loyal girl crew, her off-and-on boyfriend, and a dedicated doctor, Mari navigates a decision that could emotionally cripple the bravest of women. But both Mari and the broken-hearted baby inside her are fighters; and it doesn't take long to discover that this sick baby has the strength to heal an entire family.
