A smart, heartbreaking mystery about unexpected love, art, family, and finding yourself. It's been a year since Luna's mother, the fashion-model wife of a successful film director, was hit and killed by a taxi in New York's East Village. Luna, her father, and little brother are still struggling with grief. But when Luna goes to clean out her mother's old studio, she's stunned to find her mom's old cell phone there—charged and holding seven unheard messages. As Luna begins to listen, she learns more about her mother's life than she ever wanted to know . . . because the tidy tale she's been told about her mother's death may not be the whole truth. With the help of Oliver, the musically gifted boy next door, Luna won't stop until she finds answers. But what else will she find along the way?
