Attack Surface

Third book in the Little Brother universe, aimed at adults rather than YA readers. The protagonist is Masha, a cybersecurity contractor who has spent her career building surveillance tools for authoritarian governments and now confronts the moral weight of that work when her own community becomes a target. Darker and more morally complex than the first two books. Signed by Doctorow on a publisher's label affixed to the front free endpaper.
