Stone Heart is a gripping retelling of the story of American legend Sacajawea, the young Shoshoni woman who traveled with Lewis and Clark on their expedition to the West. Presented in Sacajawea's own voice juxtaposed with excerpts from Lewis and Clark's diaries, it is a work of moving and illuminating fiction cast from a famed piece of history that has long been masked by myth. Lewis and Clark recorded the external journey, its physical challenges and wonders. Glancy's Sacajawea experiences the expedition on a different plane, one that lies between the terrestrial and the magical, where clouds speak and ghost horses roam the plains. Both stunningly imagined and meticulously faithful to events, Stone Heart draws a lingering portrait of a woman of resilience and courage.
