Cousins Mari, Erica, Selena, and Gracie are inseparable. They aren't just family but best friends--sharing secrets, traditions, and a fierce love for their abuelita. But their idyllic childhood ends when Mari's parents divorce, forcing her to move away. With Mari gone, the girls' tight-knit bond unravels.

Fifteen years later, Mari's got the big house and handsome husband, but her life is in shambles. Erica's boyfriend just dumped her, and her new boss hates her. Selena can't seem to find her place in the world--not Mexican enough for her family, not white enough for her colleagues. And Gracie is a Catholic school teacher with an all-consuming crush, but she can't trust herself when it comes to romance.

As rocky as the cousins' lives have become, nothing can prepare them for the heartbreaking loss of a loved one. When tragedy reunites them, will they remember their abuelita's lessons about family and forgiveness--or are fifteen years of separation too much to overcome?
