Bottoms Up and the Devil Laughs - Kerry Howley
I really can't recommend this one enough. Nominally about Reality Winner in particular and the deep state in general, this book's worth reading even if you already generally know the story just because of the sheer quality of its prose.
With a secondary cast that includes John Walker Lindh, Joe Biggs and John Kiriakou, this book traces the outlines of the post-9/11 security state in a way that emphasizes its tragedy and the way living with it has warped the lives of ordinary people, pushing us to react to it in strange ways, sometimes as whistleblowers and sometimes as people who've convinced ourselves that we are but only questionably at best, as an enemy that terrible sometimes offers a convenient excuse for our actions. That double quality of our relationship to the deep state is what allowed The Intercept to functionally betray their own sources, a betrayal that forms the center of the book
Of all the many books I've read about surveillance and the security state, this is one of the best out there, and one of the few that qualifies as a masterpiece of journalism beyond the information it presents
