Continue the Story at Osaka Castle

Toyotomi Hideyori grew up inside a promise already cracking—a child raised in the shadow of a father’s unfinished empire, and a mother who would see Osaka Castle burn before she let him bow. To Ieyasu, they weren’t simply the final barrier to peace; they were the last living witnesses to what he had sworn, and what he could no longer afford to honor.

If you want to stand on the stone where that inheritance finally collapsed, A Lord, a Concubine, and a Shogun's Lie follows Hideyori’s story across the very ground where it ended.
