Dagmar Books in Order

Dagmar Shaw does not save the world with a gun or a cape. She does it with planning, nerves, contacts, and a very modern understanding of how people behave online.

That is the hook of these books.

The series follows Dagmar, a designer and producer of alternate reality games, the kind of giant clue hunts and live experiences that spill across websites, cities, phones, and crowds. Williams uses that setup to ask a smart question: what happens when skills built for play, coordination, misdirection, puzzle design, and fast trust between strangers, have to be used in actual danger?

Each book drops her into a different kind of crisis. This Is Not a Game begins with Dagmar trapped in Indonesia during unrest and then turns toward murder and conspiracy. Deep State shifts the action to Turkey, where games, surveillance, and power politics start pushing into one another. The Fourth Wall pulls some of that same pressure into entertainment culture and Hollywood, which turns out to be another system full of masks, money, and people selling versions of reality.

These are thrillers, but not old-school gadget thrillers. The technology matters because the social layer matters. Forums, crowdsourcing, performance, reputation, and collective problem-solving are part of the action, not wallpaper. Williams was early to a lot of this, and one reason the books still read well is that he understood the internet was never just about devices. It was about communities, self-invention, and how fast information could become a weapon.

Dagmar herself helps hold all that together. She is competent without feeling invulnerable, witty without turning glib, and smart enough to know that every system can fail. The books enjoy puzzles, but they are also alert to the cost of manipulation, even benevolent manipulation.

If you like near-future fiction that feels only half a step removed from the present, start at the beginning and read in order. The series builds on Dagmar's past relationships and on what each job teaches her about the blurry line between the game and the world outside it.
