It is the dawn of the New Year, 1861. After two centuries of isolation, Japan has been forced to open its doors to the West, igniting a clash of cultures and generations. And as foreign ships threaten to rain destruction on the Shogun’s castle in Edo, a small group of American missionaries has chosen this time to spread the word of their God. Among them, Emily Gibson, a woman seeking redemption from a tormented past, and Matthew Stark, a cold-eyed killer with one more death on his mind.

In the year 1311, in the highest tower of Cloud of Sparrows Castle, a beautiful woman sits by the window, watching as enemies gather below and fires spread through the night. As she calmly awaits her fate, she begins to write, carefully setting down on a scroll the secret history of the Okumichi clan…of the gift of prophecy they share and the extraordinary destiny that awaits them.
