Burgess Laughlin, an Objectivist, has published The Power and the Glory. I haven't purchased the book yet, but based on the pages available it looks interesting.
What I found curious is that the disscussion of Rand's life is based on ARI Archivist Jeff Britting's hagiographic and brief Ayn Rand. There is no mention of the two new Rand biographies (by Anne Heller and Jennifer Burns) or Barbara Branden's 1987, The Passion of Ayn Rand.
Laughlin even recommends the now-discredited The Passion of Ayn Rand's Critics by James Valliant.
