“An intriguing take on the life and times of John C. Frémont (1813–1890), explorer of the West, traveling partner of Kit Carson, California senator, unyielding abolitionist and the Republican Party's first presidential candidate (he lost the 1856 election to James Buchanan). This is not a conventional political biography but a portrait of the five-decade-long marriage between Frémont and Jessie. . . . As Denton shows, Bill and Hillary are not the first American power couple.”—Publishers Weekly
“A fascinating story of love and struggle . . . sheds light on a character only dimly known; few remember Jessie Frémont at all, let alone in her roles in the exploration of the West and the battle against slavery. Who knew that expansion and emancipation, the two great projects of nineteenth-century America, were so helped along by someone Lincoln once called ‘quite a female politician’?”—American Heritage
“[Denton] convincingly refutes popular historiography's perception of John as fortuitously marrying into a politically powerful family and coasting on his wife's talent. The Frémonts' story stretches from the advent of Manifest Destiny through the Civil War, and Denton tells the tale well, in dense but always readable detail. This original and engaging work is sure to be a boon to historians studying Old West exploration or political entanglements and military actions leading up to the Civil War.”—Library Journal
“We like to think of so-called power couples as a contemporary phenomenon, but they’ve turned up with fair regularity throughout history. . . . Journalist and historical writer Sally Denton’s fascinating double biography of John C. Frémont and his wife Jessie Benton makes a convincing case that they ought to be added to the list.”—Los Angeles Times
“Anyone who has ever imagined living life totally on his or her own terms would do well to study the lessons of Passion and Principle, Sally Denton’s lively revisionist accounting of John and Jessie Frémont. . . . Denton, whose books include American Massacre and Faith and Betrayal, is a wonderful writer, and was fortunate to have had in the Frémonts two willing helpmates. . . . Denton handily makes the case for elevating the couple’s stature in the history books.”—New York Times Book Review
"While John has many bios, this book is unique in being about both. John without Jessie is only half the story; this book completes the story in a readable, informative and enjoyable book."—James Durney, Those who can’t write, review
