The first was Bruce Schneier's Data and Goliath, which I thought was great. The second, which I'm still reading, is Lawrence Wright's Going Clear: Scientology, Hollywood, and the Prison of Belief.
Wright uses the "gender neutral masculine" throughout (as Scientology founder L. Ron Hubbard likewise seemed to do in much of his writing and thought) to refer to all human beings. So I'm find that to be pretty jarring after having had a whole year almost entirely free of that.
Don't worry though, next on my docket is Nancy Manahan's Lesbian Nuns: Breaking Silence. All will be well again in my world very soon.
