Mormonism's second prophet wasn't the famous Brigham Young -- he may have seized control of many of the Church's institutions, but he never claimed to be the "Prophet". That mantle was seized by the insteresting historic figure, James J. Strang, who led his portion of the Mormon Church from Nauvoo, Illinois, to Voree, Wisconsin, and then to Beaver Island, Michigan at the same time that Young was leading his branch to Utah.
Van Noord's book is a great biography of Strang which makes close use of Strang's journals, letters, books, and draws a great deal from the newspapers which Strang's church published. Strang's many successes both on Beaver Island and then also in the Michigan legislature, imply that he was quite a brilliant and eloquent character. The book leads you to wonder what might have happened had he not been assassinated.
The only problems with Van Noord's book are that he does not seem to be an expert in the field of Mormon history generally, and he has relied on informants in the modern Utah church -- the great rival of Strang's church -- for some of his information on Mormonism. Additionally, the biography definitely leaves you wanting a larger history of the Strangite church.
All in all, the book is an excellent read. I picked it up and nearly read it cover to cover uninterrupted, as I couldn't wait to find out what happened to Strang next.
