Though not necessarily an "easy read," I found this novel rich and rewarding, contrary to the experience of some reviewers here. Author Hall imaginatively recasts the amazing, nation-building "expedition of exploration" of Merriweather Lewis and William Clark. In an adventurous literary conceit, he weaves four voices through the narrative: co-captains Lewis and Clark, native American Sacagawea, and French Trader, Toussaint Charbonneau, finding a unique voice, eyes, and ears, for each guide along our journey. The least compelling, in my opinion, is Charbonneau; perhaps the most is Sacagawea, who probably deserved her own novel. Her passages are sometimes difficult to get through, with their lack of "Western" grammar, capitalized proper nouns, and strange punctuation, but they effectively give voice to the voiceless-despite Sacagawea's profile on the new, gold, one-dollar U.S. coin, little is truly known about her nor many other native Americans who figure in our history.
Lewis' and Clark's narrative voices are more straightforward, though no less compelling. Lewis is a tragic figure, who eventually commits suicide. Hall implies, though does not directly state, a latent homosexuality in Lewis, an unrequited love toward Clark that seems to go beyond the "brotherly" love of soldiers in arms. Clark is more confident and assured and seems to bind the voyage together. As I read the novel, I found myself on the voyage, alongside Hall's quartet, imagined much more effectively than any nonfiction account. It helps to be familiar with the story, as many of the voyage's details are left out or implied.
At the beginning of the bicentennial of this phenomenal voyage, "I Should Be Extremely Happy in Your Company" makes a great bookmark with Stephen Ambrose's classic nonfiction account, "Undaunted Courage."
