Pastor Joel Osteen's Your Best Life Now was one of the top-selling nonfiction titles during the holidays and is still going strong. Last month Warner Faith added seven cities to the author's book tour and ran ads in People and on Dr. Phil and Oprah in the top 10 markets. In addition to a January 24 Today profile, plans call for Osteen to hold major arena events this year in 15 cities, with a signing event at each stop. Since its October release, the book has sold 1.2 million copies of the 1.7 million in print.
