When Ren was twelve years old, she lost her older brother to a car accident. For twenty-five years he’s been a presence in her life, appearing with a song or a reflection in the moonlight. Her connection to the ghosts around her has made her especially sensitive as an archaeologist, understanding the bare outline of our ancestors, recreating lives and stories, and breathing life into those who occupied this world long before us. On the cusp of the most important find of her career, it is the ghosts who are guiding her way. But what they have to tell Ren about herself, and her developing relationship with the first man to really know her since her brother’s death, is unexpected—a discovery about the relationship between the past and the future, and the importance of living in the moment.
