This collection of letters bears witness to the Civil War of the common soldiers and junior officers of the Army of Tennessee. Brothers Alex and Tom Spence described to their family in detail not only the many battles in which they served, but the hardship of campaigning (they marched literally thousands of miles), the pride of serving in battle-proven units, and the pain of losing comrades to bullets and disease. The Spences were a wealthy family who owned land, slaves, and the main hotel in Arkadelphia, Arkansas. With their successful careers and extensive property, they were among Clark County's most prominent families when the shadow of secession fell across Arkansas. Four years later, Arkansas would be ravaged by war, and Tom and Alex Spence would lie in soldiers' graves, far from home. Mark Christ has assembled their powerful letters from a collection in the Old State House Museum, weaving in other letters from their extended family and friends, brief but thorough introductions to each chapter, and evocative photographs. The story moves chronologically from the outset of war to the final letter from Alex's grieving fiancée.

Tierra del Fuego is more than a suspenseful seafaring tale in the tradition of Captain Hornblower; it is also a chilling psychological and cultural tale, reminiscent of Heart of Darkness or Lord of the Flies, that probes deeply into human nature. Based on the true story of the Yámana Indian, Jemmy Button (parts of which are recorded in Chapter 10 of Charles Darwin's The Voyage of the Beagle), the novel explores Captain Robert Fitzroy's abduction of Jemmy Button and his attempt to "civilize" him in England and return him to his country as a bearer of "enlightened society." His experiment leads to tragic consequences. The novel deals with European arrogance and exploitation, but avoids falling into the cliché of "the Noble Savage." Jemmy (the "Other") remains strange and the attempt to co-opt him fails.

Tierra del Fuego has already won two major awards for the Spanish edition: The Sor Juana Inés de la Cruz Award for the best work of fiction written by a woman and The Best Book of the Year Award at the Buenos Aires Book Fair.
