In this provocative new novel, the author of Root, Petal, Thorn offers a powerful story of resilience, hope, and the secrets that, no matter how deeply hidden, can shape and ultimately unite a family. What connects us to one another? Is it shared history? Is it ancestry? Is it blood? Or is it love?  

People respond to tragedy in different ways. Some try to move on. Some don't move at all. A year after her young son's death due to a rare genetic disease, Emma Hazelton is still frozen by grief, unable and unwilling to consider her husband Noah's suggestion that they try to have another child. 

As the future Emma once imagined crumbles, her family's past comes into sharp relief. Searching for the roots of her son's disease, Emma tries to fit together the pieces in her genealogical puzzle. Hidden within an old wedding photograph of her great-grandparents is an unusual truth Emma never guessed at - a window into all the ways that love can be surprising, generous, and fiercely brave...and a discovery that may help her find her own way forward at last.
