As a child, Miryam foretells the birth of a leader who will save their people from oppression—a vision so vivid that she dedicates her life to seeing it fulfilled in her brother, Moses. But after many years, she wonders in the deepest confines of her heart if her sacrifices mean anything, if her calling is real. Tzipporah, a desert shepherdess who knows nothing of her husband"s divine purpose, suffers as he is torn from her by a strange god, a foreign people, and an unforgiving sister. In her heart, she harbors terrible secrets that haunt the love she shares with Moses and threaten her tenuous peace with Miryam. Together, Miryam and Tzipporah weave a narrative that gives voice to the women of Exodus—their lives, their community, and ultimately, their sisterhood.
