It is the dawn of the second millennium. Two royal Scottish children are swept away from their families—Macbeth to the perilous royal court of his grandfather, Gruach to the remnants of the goddess-worshiping Picts. Macbeth learns that blood bonds are easily severed while Gruach finds her path only to lose it when she’s summoned back to the patriarchal world. They struggle with gaining and losing power, guided and misguided by prophecy and politics as their paths converge in a fiery bid for royal succession. Upon the Corner of the Moon separates literary legend from reality, immersing readers in a story about the real rulers who changed the face of Scotland. Some legends are true, and the truth sometimes becomes a legend—or a lie. This novel masterfully dovetails the Macbeth legend and the truth without sacrificing either.

Deeply researched and thoughtfully constructed around themes of women's lives and spirituality, the power of storytelling, and the complex politics of northern Europe between the invasions of the Vikings and the Normans, Upon the Corner of the Moon is the first of two books telling the story of real people who’ve been rewritten into emblems of evil. “Steeped in the myth, mystery, politics, and culture of Celtic Scotland, Upon the Corner of the Moon presents the world of the young Lady Macbeth and Macbeth with authenticity, a deft hand, and a poet’s voice,” says Susan Fraser King, author of Lady Macbeth: A Novel.
