She’s brought back to vivid life by David Ebershoff, an editor at Random House who bears no grudge against Mormons but has spent the last seven years studying their genesis and considering the human costs of revelation and inerrancy. His great collage of a novel mixes the early history of the Mormon Church with the story of a modern-day murder in a breakaway Mormon cult. Readers of Under the Banner of Heaven, Jon Krakauer’s bestseller about the violent beginnings of Mormonism in the early 19th century and a double murder carried out by Mormon fundamentalists in 1984, will recognize this mingling of old and new. But Ebershoff has produced a different kind of book. For one thing, he’s made up his modern-day adventure and fictionalized the historical record to shape his own ends. And more important, he’s produced a novel that poses engaging challenges for the faithful in any denomination without discounting the essential value of faith. The result is a book packed with historical illumination, unforgettable characters and the deepest questions about the tenacity of belief.
